Fix runInTerminal failures on Windows

stella.stemenova mentioned in https://reviews.llvm.org/D93951 failures on Windows for this test.

I'm fixing the macro definitions and disabling the tests for python
versions lower than 3.7. I'll figure out that actual issue with
python3.6 after the buildbots are fine again.
