When set SEALED_SECRET to "yes", the kata-agent is built with

Today I learned, I must say.
When running a basic script, such as:
```bash
#/usr/bin/env bash
set -o errexit
set -o pipefail
set -o errtrace
cat junk && echo "hello"
echo "didn't fail"
cat junk
echo "hello"
echo "didn't fail"
```
One will get as a result:
```bash
cat: junk: No such file or directory
didn't fail
cat: junk: No such file or directory
```
Meaning that although there was an error on `cat junk && echo "hello"`,
and the `echo "hello"` part was not executed, an error was not reported
for that failure.
On the second part, though, it just breaks and returns an error as
expected.
Small scripts aside, this is exactly what was happening with the
attestation-agent, where a `make ... && make install ...` was being
called, make was failing but not actually breaking the script.
Let's change the logic and avoid such situations in the future, as it
caused our CI to be broken for quite some time without a simple way to
detect that line in the huge amount of logs left behind.
Here goes a reference to the documentation:
```
-e Exit immediately if a pipeline (which may consist
of a single simple command), a list, or a compound
command (see SHELL GRAMMAR above), exits with a
non-zero status. The shell does not exit if the
command that fails is part of the command list
immediately following a while or until keyword,
part of the test following the if or elif reserved
words, part of any command executed in a && or ||
list except the command following the final && or
||, any command in a pipeline but the last, or if
the command's return value is being inverted with
!. If a compound command other than a subshell
returns a non-zero status because a command failed
while -e was being ignored, the shell does not
exit. A trap on ERR, if set, is executed before
the shell exits. This option applies to the shell
environment and each subshell environment
separately (see COMMAND EXECUTION ENVIRONMENT
above), and may cause subshells to exit before
executing all the commands in the subshell.
If a compound command or shell function executes
in a context where -e is being ignored, none of
the commands executed within the compound command
or function body will be affected by the -e
setting, even if -e is set and a command returns a
failure status. If a compound command or shell
function sets -e while executing in a context
where -e is ignored, that setting will not have
any effect until the compound command or the
command containing the function call completes.
```

It's too long a time to cross build agent based on docker buildx, thus
we cross build rootfs based on a container with cross compile toolchain
of gcc and rust with musl libc. Then we get fast build just like native
build.
rootfs initrd cross build is disabled as no cross compile tolchain for
rust with musl lib if found for alpine and based on docker buildx takes
too long a time.

attestation-agent depends on tdx-attest-rs when cc_kbc is enabled, which
depends on libtdx-attest.so. Include the dev package in build container,
and the runtime package in the built rootfs.
The build of tdx-attest-sys (which is a dep of tdx-attest-rs) uses
bindgen, which requires libclang so install that in the build container
as well.
We specify the tdx stack DCAP v1.15

CentOS and the init service is systemd, not the agent init. To enable
labeling the guest image on the host, selinuxfs must be mounted on the
host. The kata-agent will be labeled as `container_runtime_exec_t` type.

It would be nice to use `versions.yaml` for the maintainability.
Previously, we have been specified the `libseccomp` and the `gperf` version
directly in this script without using the `versions.yaml` because the current
snap workflow is incomplete and fails.
This is because snap CI environment does not have kata-cotnainers repository
under ${GOPATH}. To avoid the failure, the `rootfs.sh` extracts the libseccomp
version and url in advance and pass them to the `install_libseccomp.sh` as
environment variables.

In at least kata versions 2.3.3 and 2.4.0 it was noticed that the guest
operating system's clock would drift out of sync slowly over time
whilst the pod was running.
This had previously been raised and fixed in the old reposity via [1].
In essence kvm_ptp and chrony were paired together in order to
keep the system clock up to date with the host.
In the recent versions of kata metioned above,
the chronyd.service fails upon boot with status `266/NAMESPACE`
which seems to be due to the fact that the `/var/lib/chrony`
directory no longer exists.
This change sets the `/var/lib/chrony` directory for the `ReadWritePaths`
to be ignored when the directory does not exist, as per [2].

Remove a lot of cruft of musl installations -- we needed those for the
Go agent, but Rustup just takes care of everything. aarch64 on
Debian-based & Alpine is an exception -- create a symlink
`aarch64-linux-musl-gcc` to `musl-tools`'s `musl-gcc` or `gcc` on
Alpine. This is unified -- arch-specific Dockerfiles are removed.
Furthermore, we should keep it in Ubuntu for supporting the offline SEV
KBC. We also keep it in Clear Linux, as that runs our internal checks,
but it is e.g. not shipped in CentOS Stream 9.
