[libvirt] [PATCH v2 5/5] apparmor: allow to preserve /dev mountpoints into qemu namespaces

Libvirt now tries to preserve all mounts under /dev in qemu namespaces. The old rules only listed a set of known paths but those are no more enough. I found some due to containers like /dev/.lxc/* and such but also /dev/console and /dev/net/tun. Libvirt is correct to do so, but we can no more predict the names properly, so we modify the rule to allow a wildcard based pattern matching what libvirt does.
