apparmor: fix mediation of prlimit
For primit apparmor requires that if target confinement does not match
the setting task's confinement, the setting task requires CAP_SYS_RESOURCE.
Unfortunately this was broken when rlimit enforcement was reworked to
support labels.
Fixes: 86b92cb782b3 ("apparmor: move resource checks to using labels")
