[PRQ#42236] Deletion Request for python-arg

MarsSeed [1] filed a deletion request for python-arg [2]: One-commit Python code, made in 2017, and makefile changed in 2021. But now GitHub repo is inactivated, archived. [a] Nothing depends on it, there are no comments. Python2 subpackage even has wrong dependency. It seems best to delete this.
