Fix an infinite loop in setnetgrent(3) with NIS netgroups.

Handle an empty result from yp_match() by returning NULL, which is
consistent with the handling of an empty netgroup in /etc/netgroup.
setnetgrent(3) has no return value, so there is no particular need to
distinguish this case from an error.
