[libvirt] [PATCH] Allow rbd backing stores



Prevents libvirt from treating RBD backing stores as files. Without this patch,
creating a domain with a qcow2 overlay on an RBD would fail.

This patch essentially extends 9c7c4a4fc533598e59e9a0038ec783e61a38e664,
which allows nbd backing stores, to allow rbd backing stores.
