tests.haskell.ghcWithPackages: init 

`ghcWithPackages` broke in #411741, partially because we don't have
tests for it. This adds some tests to make sure it keeps working in the
future. For now these tests will fail until #415436 is fixed.

This is split off of #415434.

Adds a regression test for https://github.com/NixOS/nixpkgs/pull/224542
