Fix 4 warnings in /games reported by Clang Static Analyzer:
bcd and caesar are not installed SETGID (at least on my system). Remove the
call to setgid() as it becomes redundant.
In fortune, make sure a tail file is passed in the args if mandated in the
logic. Bail if not.
In random(6), fix a memory leak in randomize_fd()
