Upstream apparmor is switching to named profiles. Many profiles have
already made the switch. Patch 1 changes the libvirtd profile to
account for dnsmasq's switch to a named profile.
Patch 2 is optional and changes the libvirtd profile to a named profile.
It will need a bit of coorindation with upstream apparmor since the dnsmasq
profile currently has 'peer=/usr/sbin/libvirtd'.

New subject: [libvirt] [PATCH 1/2] apparmor: Add support for named profiles
Upstream apparmor is switching to named profiles. In short,
/usr/sbin/dnsmasq {
becomes
profile dnsmasq /usr/sbin/dnsmasq {
Consequently, any profiles that reference profiles in a peer= condition
need to be updated if the referenced profile switches to a named profile.
Apparmor commit 9ab45d81 switched dnsmasq to a named profile. ATM it is
the only named profile switch that has affected libvirt. Add rules to the
libvirtd profile to reference dnsmasq in peer= conditions by profile name.

This also LGTM. It'd be nice if there was a mechanism to specify the parent
profile like we can the current profile, but we can't now and this is fine.

Thanks for reviewing these patches! I've pushed them now.
