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") Signed-off-by: John Johansen <john.johansen@canonical.com>
