  mgetgroups: add xgetgroups, and avoid ENOSYS failures
  
  ENOSYS implies that there are no supplemental groups, so we can
  treat it the same as a return of 0 from getgroups rather than
  exposing failure to the user.  This in turn fixes a crash in
  coreutils' id, which freed an uninitialized pointer.
  
  * lib/mgetgroups.h (xgetgroups): New prototype.
  * lib/mgetgroups.c (xgetgroups): New wrapper.
  (mgetgroups): Handle ENOSYS.
  * modules/mgetgroups (Depends-on): Add realloc.
