clatd calls mmap(MAP_LOCKED) with a 1M buffer. MAP_LOCKED first checks capable(CAP_IPC_LOCK), and then checks to see the requested amount is under RLIMIT_MEMLOCK. The latter check succeeds. As a result, clatd does not need CAP_IPC_LOCK, so we suppress any denials we see from clatd asking for this capability.
