[libvirt] [PATCH] apparmor: QEMU bridge helper policy updates



This patch provides AppArmor policy updates for the QEMU bridge helper.
The QEMU bridge helper is a SUID executable exec'd by QEMU that drops
capabilities to CAP_NET_ADMIN and adds a tap device to a network
bridge. For more details on the helper, please refer to:
