get_dirs_from_args handles paths with invalid syntax

Fix #7638

I don't have a windows machine to test, but by the removal of the sys.version_info < (3, 8) check I assume this (OSError on invalid syntax) can happen even on Python>=3.8? If so it might be worth reporting to Python upstream, it's just really annoying that these methods can raise and they already changed it do the right thing regarding "unrepresentable characters" (ref second paragraph).

Regarding the needs backport label, I think this problem only happens in the new pathlib code which is not in 6.0.x. The AppVeyor run you linked seems to confirm it only fails on master. So IIUC it doesn't need a backport.

Good point, was about to report it but then noticed that was already the case: https://bugs.python.org/issue35306

I've added that link as a comment. 👍

You are definitely correct, thanks!
