Subject: [PATCH v2 3/3] kunit: tool: fix pre-existing `mypy --strict` errors
and update run_checks.py
Basically, get this command to be happy and make run_checks.py happy
$ mypy --strict --exclude '_test.py$' --exclude qemu_configs/ ./tools/testing/kunit/
Primarily the changes are
* add `-> None` return type annotations
* add all the missing argument type annotations
Previously, we had false positives from mypy in `main()`, see commit
09641f7c7d8f ("kunit: tool: surface and address more typing issues").
But after commit 2dc9d6ca52a4 ("kunit: kunit.py extract handlers")
refactored things, the variable name reuse mypy hated is gone.
Note: mypy complains we don't annotate the types the unused args in our
signal handler. That's silly.
But to make it happy, I've copy-pasted an appropriate annotation from
https://github.com/python/typing/discussions/1042#discussioncomment-2013595.
