Subject: [PATCH net-next v3 01/12] selftests: net: py: coding style improvements

We're about to add more features here and finding new issues with old
ones in place is hard. Address ruff checks:
 - bare exceptions
 - f-string with no params
 - unused import

We need to use BaseException when handling defer(), as Petr points out.
This retains the old behavior of ignoring SIGTERM while running cleanups.
