In order to let upcall being used by Kata Container, we need to add
those patches into kernel build script.
Currently, only when experimental (-e) and hypervisor type dragonball
(-t dragonball) are both enabled, that the upcall patches will be
applied to build a 5.10 guest kernel.
example commands: sh ./build-kernel.sh -e -t dragonball -d setup

Upcall is a direct communication tool between VMM and guest developed
upon vsock. The server side of the upcall is a driver in guest kernel
(kernel patches are needed for this feature) and it'll start to serve
the requests after the kernel starts. And the client side is in
Dragonball VMM , it'll be a thread that communicates with vsock through
uds.
We want to keep the lightweight of the VM through the implementation of
the upcall, through which we could achieve vCPU hotplug, virtio-mmio
hotplug without implementing complex and heavy virtualization features
such as ACPI virtualization.

CONFIG_X86_SGX is introduced after kernel 5.11, and that config is a
default x86_64 config for Kata build-kernel.sh script.
But if we use -v to specify any kernel version below 5.11 will cause an
inevitable error because CONFIG_X86_SGX is not supported in older
kernels and that may cause problem for the situation if we need kernel
version below 5.11.
So I propose to put CONFIG_X86_SGX into whitelist.conf to avoid break
building guest kernel below 5.11.

The previously used repo has been removed by Intel. As this happened,
the TDX team worked on providing the patches that were hosted atop of
the v5.15 kernel as a tarball present in the
https://github.com/intel/tdx-tools repos, see
https://github.com/intel/tdx-tools/pull/161.
On the Kata Containers side, in order to simplify the process and to
avoid adding ~1400 kernel patches to our repo, we've revived the
https://github.com/kata-containers/linux repo, and created a branch and
a tag with those ~1400 patches atop of the v5.15. The branch is called
v5.15-plus-TDX, and the tag is called 5.15-plus-TDX (in order to avoid
having to change how the kernel builder script deals with versioning).
Knowing the whole background, let's switch the repo we're getting the
TDX kernel from.

00aadfe20a introduced a regression on
`make cc-tdx-kernel-tarball` as we stopped passing all the needed
information to the `build-kernel.sh` script, leading to requiring `yq`
installed in the container used to build the kernel.
This commit partially reverts the faulty one, rewritting it in a way the
old behaviour is brought back, without changing the behaviour that was
added by the faulty commit.
