Subject: test: split up integration_tests

...into "matrix" and "normal".

Also:
* Make running multiple packages in parallel safe, see
  http://stackoverflow.com/questions/23715302/go-how-to-run-tests-for-multiple-packages
* Don't depent on test_helper.TmpDir and friends to have a terminating slash
