I guess it would be better if NOCRED/FSCRED is handled in
kauth_cred_geteuid() (and other kauth_cred_... routines).

In case of kauth_cred_geteuid(), it will be natual if 0 is returned when
NOCRED/FSCRED is passed to, since kauth_authorize_action_internal()
always returns KAUTH_RESULT_ALLOW for them.
