Support default profile for apparmor

Currently you can not apply an ApparmorProfile if you specify
--privileged.  This patch will allow both to be specified
simultaniosly.

By default Apparmor should be disabled if the user
specifies --privileged, but if the user specifies --security apparmor:PROFILE,
with --privileged, we should do both.
