Normalize paths

Fixes #364.

Test failures look unrelated (a Codecov API rate limiting issue).

I agree the coverage jobs are probably a ci configuration issue and can be ignored. But the windows jobs are failing too.
It looks like there is an issue on windows that ci is catching here: https://github.com/mtreinish/stestr/actions/runs/10595299313/job/29361543634?pr=365#step:6:7049

[stephenfin]

Good point. Fixed those. I also pinched part of Takashi-san's tox 4 compat change (#360) so I could actually test this locally (though not actually on Windows sadly). We might want to merge that entire PR at some point.

EDIT: Nope, still not working. os.path.normpath says:

On Windows, it converts forward slashes to backward slashes

So where is tests/test_passing coming from? 😕

EDIT: Okay, actually fixed now. Another test was failing 🤦
