The current apparmorfs interface is compatible with previous versions

APPARMOR_COMPAT_24) and replace it with a more sysfs style single

We don't usually merge compatibility code to handle ABIs that were
developed out-of-tree. Why should we treat AppArmor differently?
I would say that always depends on the deployed base of the old ABI.
If there's a lot of users who would get broken I think there's a
good case for merging compat code (I don't know if that is or
isn't the case here).
A widely used distribution release with the old user land would
probably count.
