Enable seccomp support in `runk` by default.
Due to this, `runk` is built with `gnu libc` by default
because the building `runk` with statically linked the `libseccomp`
and `musl` requires additional configurations.
Also, general container runtimes are built with `gnu libc` as
dynamically linked binaries by default.
The user can disable seccomp by `make SECCOMP=no`.

Refactor the container builder code (`InitContainer` and `ActivatedContainer`)
to make it easier to understand and to maintain.
The details:
1. Separate the existing `builder.rs` into an `init_builder.rs` and
`activated_builder.rs` to make them easy to read and maintain.
2. Move the `create_linux_container` function from the `builder.rs` to
`container.rs` because it is shared by the both files.
3. Some validation functions such as `validate_spec` from `builder.rs`
to `utils.rs` because they will be also used by other components as
utilities in the future.

To make cgroup v1 and v2 works well, I use `cgroups::cgroup` in
`Container` to manager cgroup now. `CgroupManager` in rustjail has some
drawbacks. Frist, methods in Manager traits are not visiable. So we need
to modify rustjail and make them public. Second, CgrupManager.cgroup is
private too, and it can't be serialized. We can't load/save it in
status file. One solution is adding getter/setter in rustjail, then
create `cgroup` and set it when loading status. In order to keep the
modifications to a minimum in rustjail, I use `cgroups::cgroup`
directly. Now it can work on cgroup v1 or v2, since cgroup-rs do this
stuff.

ps command supprot two formats, `json` and `table`. `json` format just
outputs pids in the container. `table` format will use `ps` utilty in
the host, search and output all processes in the container. Add a struct
`container` to represent a spawned container. Move the `kill`
implemention from kill.rs as a method of `container`.

`exec` will execute a command inside a container which exists and is not
frozon or stopped. *Inside* means that the new process share namespaces
and cgroup with the container init process. Command can be specified by
`--process` parameter to read from a file, or from other parameters such
as arg, env, etc. In order to be compatible with `create`/`run`
commands, I refactor libcontainer. `Container` in builder.rs is divided
into `InitContainer` and `ActivatedContainer`. `InitContainer` is used
for `create`/`run` command. It will load spec from given bundle path.
`ActivatedContainer` is used by `exec` command, and will read the
container's status file, which stores the spec and `CreateOpt` for
creating the rustjail::LinuxContainer. Adapt the spec by replacing the
process with given options and updating the namesapces with some paths
to join the container. I also rename the `ContainerContext` as
`ContainerLauncher`, which is only used to spawn process now. It uses
the `LinuxContaier` in rustjail as the runner. For `create`/`run`, the
`launch` method will create a new container and run the first process.
For `exec`, the `launch` method will spawn a process which joins a
container.

Support list sub-command. It will traverse the root directory, parse

runk always launches containers with detached mode,
so users have to use a console socket with run or
create operation when a terminal is used.
If users set `terminal` to `true` in `config.json` and
try to launch a container without specifying a console
socket, runk returns an error with a message early.

This commit enables runk to handle `root.path` in `config.json`
properly even if the path is specified by a relative path that
includes the single (`.`) or the double (`..`) dots.
For example, with a bundle at `/to/bundle` and a rootfs directly
under `/to/bundle` such as `/to/bundle/{bin,dev,etc,home,...}`,
the `root.path` value can be either `/to/bundle` or just `.`.
This behavior conforms to OCI runtime spec.
Accordingly, a bundle path managed by runk's status file
(`status.json`) always is statically stored as a canonical path.
Previously, a bundle path has been got by `oci_state()` of rustjail's
API that returns the path as the parent directory path of a rootfs
(`root.path`). In case of the kata-agent, this works properly because
the kata containers assume that the rootfs path is always
`/to/bundle/rootfs`. However in case of standard OCI runtimes,
a rootfs can be placed anywhere under a bundle, so the rootfs path
doesn't always have to be at a `/to/bundle/rootfs`.

runk uses liboci-cli crate to parse command line options,
but liboci-cli does not support --all option for kill command,
though this is the runtime spec behavior.
But crictl will issue kill --all command when stopping containers,
as a workaround, we use a custom kill command instead of the one
provided by liboci-cli.
