PL/Python: Remove procedure cache invalidation
This was added to react to changes in the pg_transform catalog, but
building with CLOBBER_CACHE_ALWAYS showed that PL/Python was not
prepared for having its procedure cache cleared. Since this is a
marginal use case, and we don't do this for other catalogs anyway, we
can postpone this to another day.
