pgsql: Add a #define for the inet overlaps operator.

Add a #define for the inet overlaps operator.

Extracted from pending inet selectivity patch.  The rest of it isn't
quite ready to commit, but we might as well push this part so the patch
doesn't have to track the moving target of pg_operator.h.
