getgroups: avoid calling exit rpl_getgroups should be a library function, comparable to glibc. * modules/getgroups (Depends-on): Add malloc-posix and unistd, drop xalloc. * modules/getgroups-tests (Depends-on, Makefile.am): Drop unneeded dependencies. * lib/getgroups.c (rpl_getgroups): Fail with ENOMEM rather than exiting, in the rare case of malloc failure.
