id: handle (uid_t) -1 more portably

* src/id.c (GETID_MAY_FAIL): Remove.
(main): Check for nonzero errno, rather than having a compile-time
GETID_MAY_FAIL guess.  Suggested by Roland McGrath in
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10021#47>.
Also, the old code was incorrect if uid_t was narrower than int.
(print_full_info): Remove unnecessary cast to -1.
