[2/3] kunit: tool: unit tests all check parser errors, standardize formatting a bit

  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`.

I'll send a v2 that's rebased to avoid issues applying them.
