More configurability for secondary group lookup

Together with a previous patch which introduced the initgroups
entry in nsswitch.conf this patch allows more customization of
the lookups for initgroups/getgrouplist.  Nothing changes if
the groups entry in nsswitch.conf is used.  If the initgroups entry
is used instead the code now doesn't automatically continue looking
for more entries aftedr a successful lookup.  Instead the normal
rules are followed which do specify that by default no more
service is consulted.  This can be overwritten with
	[SUCCESS=continue]
appropriately placed in the line.
