apparmor: fix setting unconfined mode on a loaded profile
When loading a profile that is set to unconfined mode, that label
flag is not set when it should be. Ensure it is set so that when
used in a label the unconfined check will be applied correctly.
Fixes: 038165070aa5 ("apparmor: allow setting any profile into the unconfined state")
