test: Add a exec test case for terminated successfully

[lifupan]

When an exec forked some daemon process which would inherit its stdio fds, thus when the exec main process exited, its io stream wouldn't terminated, even at this case, we should make sure the exec terminated successfully without hang there.

Fixes: #4972

hi @lifupan , would make sense to exec on the container afterwards to also check the tail process is still alive?

[liubin]

@wainersm give us a good advice, so I will add the DNM label.

As we're in the process (a still long process) of moving tests from this repo to the kata-containers one, we're closing PRs that are either stale for too long.

Please, if you think this has been mistakenly closed, open it agains the kata-containers repo as in the coming months this repo will be archived.
