Explicitly filter out partial groups when we don't want them

Instead of hacking OutputGroup::m_ancestors to discourage the inclusion
of partial groups via the eligibility filter, add a parameter to the
eligibility filter that indicates whether we want to include the group.
Then for those partial groups, don't return them in GroupOutputs if we
indicate they aren't desired.
