Log Message:
suppress duplicate gids (e.g, when multiple sources are given in
nsswitch.conf and they contain similar information).

XXX: in the case where the given array is too small and -1 is returned,
the returned ngroups will be too large by a factor of the difference
between the given size and the number of matches. this is not considered
to be a major problem, since it's still going to be a smaller figure than
what the previous (non suppressive) behaviour returned.
