This primarily comes from running pylint over kunit tool code and
ignoring some warnings we don't care about.
If we ever got a fully clean setup, we could add this to run_checks.py,
but we're not there yet.
Fix things like
* Drop unused imports
* check `is None`, not `== None` (see PEP 8)
* remove redundant parens around returns
* remove redundant `else` / convert `elif` to `if` where appropriate
* rename make_arch_qemuconfig() param to base_kunitconfig (this is the
name used in the subclass, and it's a better one)
* kunit_tool_test: check the exit code for SystemExit (could be 0)

We're missing the `f` prefix to have python do string interpolation, so
we'd never end up printing what the actual "unexpected" error is.

This formalizes the checks KUnit maintainers have been running (or in
other cases: forgetting to run).
This script also runs them all in parallel to minimize friction (pytype
can be fairly slow, but not slower than running kunit.py).
Example output:
$ ./tools/testing/kunit/run_checks.py
Waiting on 4 checks (kunit_tool_test.py, kunit smoke test, pytype, mypy)...
kunit_tool_test.py: PASSED
mypy: PASSED
pytype: PASSED
kunit smoke test: PASSED
On failure or timeout (5 minutes), it'll dump out the stdout/stderr.
E.g. adding in a type-checking error:
mypy: FAILED
> kunit.py:54: error: Name 'nonexistent_function' is not defined
> Found 1 error in 1 file (checked 8 source files)
mypy and pytype are two Python type-checkers and must be installed.
This file treats them as optional and will mark them as SKIPPED if not
installed.
This tool also runs `kunit.py run --kunitconfig=lib/kunit` to run
KUnit's own KUnit tests and to verify KUnit kernel code and kunit.py
play nicely together.
It uses --build_dir=kunit_run_checks so as not to clobber the default
build_dir, which helps make it faster by reducing the need to rebuild,
esp. if you're been passing in --arch instead of using UML.
