In the case of the TAP output having an incorrect header format, the parser used to output an error message of 'no tests run!'. Additionally, in the case of TAP output with the correct header but no tests, the parser used to output an error message of 'could not parse test results!'. This patch corrects the error messages for these two cases by switching the original outputted error messages and correcting the tests in kunit_toot_test.py.

You might want to include an example like this in your commit description:
Before: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] no tests run! ...
After: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] could not parse test results! ...
We could also include an example with a header but 0 tests, but I think /dev/null illustrates this enough. But if we wanted to:
Before: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] could not parse test results!
After: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] no tests run!

Can we truncate this log down to a smaller one w/ just the essential bits? I don't know that printing out lines about Brendan's workstation is necessarily relevant to the test :)
The main part we need is
+TAP version 14 +1..0
I know this is just copying from what we had before in the "no_header" version, but it feels a bit excessive to have all this.
