Handle multiple user names with the same UID better. (#319535, Laszlo

	Handle multiple user names with the same UID better.
	(#319535, Laszlo Peter)

	* glib/gutils.c (g_get_any_init_do): When determining user
	data, first look up $LOGNAME. If the UID doesn't match
	getuid(), fall back to the current behaviour of looking
	up the user data based on getuid().
