Verify that used OCI runtime supports checkpoint

Browse Source 
To be able to use OCI runtimes which do not implement checkpoint/restore
this adds a check to the checkpoint code path and the checkpoint/restore
tests to see if it knows about the checkpoint subcommand. If the used
OCI runtime does not implement checkpoint/restore the tests are skipped
and the actual 'podman container checkpoint' returns an error.
