Subject: [PATCH] rework (live) migration tests

In particular, same-host-different-lxd migration doesn't work right now
because of some cgroup path issues. CRIU will need to learn how to rewrite
mount paths to support this use case, but it's not a super high priority
right now.

Instead, let's use stateful snapshot/restore which will work, so that we
can at least test the CRIU machenery.
