In the Ubuntu development release we recently got a new udev that
moves /var/run to /run, /var/lock to /run/lock and /dev/shm to /run/shm.
This change in udev requires updating the apparmor security driver in
libvirt[1].

Attached is a patch that:
 * adjusts src/security/virt-aa-helper.c to allow both
LOCALSTATEDIR/run/libvirt/**/%s.pid and /run/libvirt/**/%s.pid. While
the profile is not as precise, LOCALSTATEDIR/run/ is typically a symlink
to /run/ anyway, so there is no additional access (remember that
apparmor resolves symlinks, which is why this is still required even
if /var/run points to /run).
 * adjusts example/apparmor/libvirt-qemu paths for /dev/shm
