We may just skip the test if the script is not installed.

On my system: py -3.n -m test.test_regrtest (or test test_regrtest) fails for n in {5, 6, 7}.  2.7 runs, but there are far fewer test methods. Repository builds work fine.

The fix is simple, skip the test if the script doesn't exist at:

    def test_pcbuild_rt(self):
        # PCbuild\rt.bat
        script = os.path.join(ROOT_DIR, r'PCbuild\rt.bat')

I'm not sure that Python 3.6. In case of doubt, I prefer to skip it.

The bug has been fixed in Python 3.7 and master. Thanks Andrés Delfino for your nice contribution!
