Add test case for container migration 

The difference between container checkpoint/restore and container
migration is that for migration the container which was checkpointed
must not exist during restore. To simulate migration the container
is remove ('podman rm -fa') before being restored. The migration test
does following steps:

 * podman run
 * podman container checkpoint -l -e /tmp/checkpoint.tar.gz
 * podman rm -fa
 * podman container restore -i /tmp/checkpoint.tar.gz
