kunit: tool: undo type subscripts for subprocess.Popen Writing `subprocess.Popen[str]` requires python 3.9+. kunit.py has an assertion that the python version is 3.7+, so we should try to stay backwards compatible. This conflicts a bit with commit 1da2e6220e11 ("kunit: tool: fix pre-existing `mypy --strict` errors and update run_checks.py"), since mypy complains like so > kunit_kernel.py:95: error: Missing type parameters for generic type "Popen" [type-arg] Note: `mypy --strict --python-version 3.7` does not work. We could annotate each file with comments like `# mypy: disable-error-code="type-arg" but then we might still get nudged to break back-compat in other files. This patch adds a `mypy.ini` file since it seems like the only way to disable specific error codes for all our files. Note: run_checks.py doesn't need to specify `--config_file mypy.ini`, but I think being explicit is better, particularly since most kernel devs won't be familiar with how mypy works.
