[libvirt] [PATCH 2/2] AppArmor: use fine-grained mount rules instead of a blanket catch-all one

[intrigeri+libvirt at boum.org]

From: intrigeri <intrigeri+libvirt at boum.org>

This set of rules was proposed by Christian Boltz <apparmor at cboltz.de>
on https://bugzilla.opensuse.org/show_bug.cgi?id=1065123.
