postgresql: remove thisAttr argument by calling tests directly
Previously, it was not possible to run tests on an overridden derivation, because
the derivation under test was always pulled from pkgs.
With this change, the following will return the same test:
postgresql_jit.tests
and
(postgresql.override { jitSupport = true; }).tests
