"make check" fails on Kali Linux, because the machinery lacks pieces:
- Add mypy, yapf3, python3-pyright to project.conf for Debian. The
pyright package is not in upstream Kali, but is now supplied by
the jw-foss repo.
- ifdef ruff out from "make check" in py-topdir.mk, because it's
too much work to get that to work from packages on Kali Linux for
now.
