libpod: read exit code when cleaning up the runtime

While for some call paths we may be doing this redundantly we need to
make sure the exit code is always read at this point.

[NO NEW TESTS NEEDED] as I do not manage to reproduce the issue which
is very likely caused by a code path not writing the exit code when
running concurrently.

Fixes: #14859
