Without this, we can output a mixture of '/' and '\' on platforms where
os.path.sep is '\' and prefix or outdir uses '/'. Let's always return
the path in the format of the platform we're running on.
This is needed to make the test_install_introspection() unittest work
properly on Windows.
Otherwise trying to introspect tests might lead to:
