[libvirt] [PATCH] Run 'cont' on successful migration finish.

As of qemu 0.10.6, qemu now honors the -S flag on incoming migration. That means that when the migration completes, we have to issue a 'cont' command to get the VM running again. We do it unconditionally since it won't hurt on older qemu.
