getgroups: work around FreeBSD bug

FreeBSD 7.2 mistakenly succeeds on getgroups(-1,ptr) (POSIX
requires EINVAL failure since -1 is less than the proper result).

* lib/getgroups.c (rpl_getgroups): Work around the bug.
* m4/getgroups.m4 (gl_FUNC_GETGROUPS): Detect the bug.
* doc/posix-functions/getgroups.texi (getgroups): Document it.
* tests/test-getgroups.c (main): Fix buffer overrun.
