windows: simply rely on the PATH adjustment to find python.exe in tests

The shell script under a `.exe` name confused Windows outside MSYS and give us
the following error:

    […]/python.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

This is necessary to get the wheel variant of the test run to work properly.

# Test that certain objects conform to well-defined interfaces.
