1) Remove explicit allow statements. Since su is in permmissive,
there's no need to ever specify allow statements for su.
2) Remove unconfined_domain(su). Su is already permissive, so there's
no need to join the unconfined domain, and it just makes getting
rid of unconfined more difficult.
3) Put su into app_domain(). This addresses, in a roundabout sorta
way, the following denial:
type=1400 audit(0.0:4): avc: denied { setsched } for scontext=u:r:system_server:s0 tcontext=u:r:su:s0 tclass=process permissive=0
which comes up while testing media processes as root. We already put
the shell user into this domain, so adding su to this domain ensures
other processes can communicate consistently with su spawned processes.
