In a common Debian/Ubuntu installation those are in fact in /usr/lib/libvirt/
So this change would break us.
To me it seems the current content matches the distro's with apparmor in place.
Not sure about Suse here atm.
But if we are changing that we should consider making this dependent
on --libexecdir as this is where this path really comes from.
And Debian/Ubuntu are setting --libexecdir=\${prefix}/lib/libvirt at
config time.
