testsuite: Use Cabal's new test suite interface

  * The old way: a user hook in Setup.hs
  * The new way: specify it in gf.cabal
  * The test suite is now called gf-tests, and it runs testsuite/run.hs.
  * You can run it manually with 'runhaskell testsuite/run.hs'. It also runs,
    together with rgl-tests, when you do 'cabal test'
  * Currently only 9 of 34 tests pass. Many failures have silly causes:
    - Error messages that look slightly different
    - Same output but in a different order
    - Absolute paths in output
