Range_transitions are expanded in the qpol representation, but attributes
can still be used as criteria.
Hard code default role to indirect to handle role attributes in the
criteria. Role attributes don't survive in the qpol
representation yet, so this is a forward-looking change.
Similarly hard code the default type matching to indirect so attributes can
be used for default type criteria in type_* rules. Adjust default criteria
lookup function accordingly.
