Since we're using Python 3.7+, we can use dataclasses to tersen the
code.

It also lets us create pre-populated TestCounts() objects and compare
them in our unit test. (Before, you could only create empty ones).

Let's verify that the parser isn't reporting any errors for valid
inputs.

This change also
* does result.status checking on one line
* makes sure we consistently do it outside of the `with` block

Looks good, thanks.

Note that this patch does conflict with "kunit: tool: print summary of
failed tests if a few failed out of a lot":
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/commit/?h=kunit&id=f19dd011d8de6f0c1d20abea5158aa4f5d9cea44
It's only a context line issue, though.

Oh huh, I rebased onto the kunit branch and it managed to merge cleanly.
I guess `git am` is more picky than `git rebase`.

We're using a `with` block above, so the file object is already closed.
