KEYS: Make /proc/keys check to see if a key is possessed before security check
Make /proc/keys check to see if the calling process possesses each key before
performing the security check. The possession check can be skipped if the key
doesn't have the possessor-view permission bit set.
This causes the keys a process possesses to show up in /proc/keys, even if they
don't have matching user/group/other view permissions.
