* mkgroup.c (fetch_current_pgrp_sid): New function to fetch primary 

group SID from user token.
	(current_group): Move up in file.  Move fetching primary group SID to
	fetch_current_pgrp_sid.
	(enum_local_groups): Check if current SID is the same as current user's
	primary group SID.
	(enum_groups): Ditto.
	(main): Call fetch_current_pgrp_sid before enumerating groups.  Call
	current_group only if current group hasn't been enumerated already.
	* mkpasswd.c (fetch_current_user_sid): New function to fetch current
	user SID from user token.
	(current_user): Move fetching current user SID to
	fetch_current_user_sid.
	(enum_users): Check if current SID is the same as current user's SID.
	(main): Call fetch_current_user_sid before enumerating users.  Call
	current_user only if current user hasn't been enumerated already.
