apparmor: fix profile attachment for special unconfined profiles
It used to be that unconfined would never attach. However that is not
the case anymore as some special profiles can be marked as unconfined,
that are not the namespaces unconfined profile, and may have an
attachment.
Fixes: f1bd904175e8 ("apparmor: add the base fns() for domain labels")
