Postcopy seems to have survived a cycle with only a few fixes,
and Jiri has the current libvirt wired up and working
( https://www.redhat.com/archives/libvir-list/2016-March/msg00080.html )
so remove the experimental tag.

To enable postcopy, issue this command on the monitor prior to the
start of migration:
-migrate_set_capability x-postcopy-ram on
+migrate_set_capability postcopy-ram on
The normal commands are then used to start a migration, which is still
started in precopy mode. Issuing:
