[PATCH v2 5/5] apparmor: let qemu load old shared objects after upgrades

Since [1] qemu can after upgrade fall back to pre-upgrade modules to still be able to dynamically load qemu-module based features. The paths for these modules are pre-defined by the code and should be allowed to be mapped and loaded from which will allow packagers avoiding the inability of late feature load [2] after package upgrades.
