Hrmm, these rules were never meant to last as long as they have. That
said, they are already a part of the AppArmor base abstraction (using
owner match though) and virt-aa-helper uses '#include
<abstractions/base>'. Are these rules still needed considering the base
abstraction? I imagine at worst virt-aa-helper would only need 'r' for
some of these...
