Remove MODULES_big from test_pg_dump

The Makefile for test_pg_dump shouldn't have a MODULES_big line
because there's no actual compiled bit for that extension.  Hopefully
this will fix the Windows buildfarm members which were complaining.

In passing, also add the 'prove_installcheck' bit to the pg_dump and
test_pg_dump Makefiles, to get the buildfarm members to actually run
those tests.
