Make has_sequence_privilege support WITH GRANT OPTION

The various has_*_privilege() functions all support an optional
WITH GRANT OPTION added to the supported privilege types to test
whether the privilege is held with grant option. That is, all except
has_sequence_privilege() variations. Fix that.

Back-patch to all supported branches.
