fix(gnodev): fix the use of filepath instead of path on windows (#3737)

fix #3722

Using `filepath` to work with the `path` creates some obvious issues on
Windows, primarily because the `Clean` function replaces `/` with `\\`.
This PR updates the usage of `filepath` to `path` where necessary.

At some point, adapting path-specific tests on Windows would be very
helpful.

@Milosevic02, can you confirm that this fix resolves most of your issues
with gnodev?

**EDIT:** It seems that the fix is effective:
