apparmor: rename apparmor file fns and data to indicate use
prefixes are used for fns/data that are not static to apparmorfs.c
with the prefixes being
aafs - special magic apparmorfs for policy namespace data
aa_sfs - for fns/data that go into securityfs
aa_fs - for fns/data that may be used in the either of aafs or
securityfs
