bats: add bats-tested packages to passthru.tests

It would have been ~easy for someone to update bats without noticing
whether the update broke any packages that depend directly on the
nixpkgs-packaged bats for their tests. (I'm phrasing this tediously
because there are also some packages that vendor a copy of bats.)

Hopefully this will make it easier to confirm future updates.
