If I created a kunitconfig file that was incomplete, then $ ./tools/testing/kunit/kunit.py build --kunitconfig=my_kunitconfig would silently drop all the options with unmet dependencies!

This is because it doesn't do the config check that `kunit.py config` does.

So if I want to safely build a kernel for testing, I have to do $ ./tools/testing/kunit/kunit.py config <flags> $ ./tools/testing/kunit/kunit.py build <flags, again>

It seems unlikely that any user of kunit.py would want the current `build` semantics. So make it effectively do `kunit.py config` + `kunit.py build`.
