Add parsing of attributes as diagnostic data. Fixes issue with test plan
being parsed incorrectly as diagnostic data when located after
suite-level attributes.

Note that if there does not exist a test plan line, the diagnostic lines
between the suite header and the first result will be saved in the suite
log rather than the first test case log.

Note this patch is a resend but I removed the second patch in the series
so now it is a standalone patch.

This seems sensible to me, though I'd love to have a test to go along
with it (or at least an example input which shows the problem).

Indeed, none of the logs in tools/testing/kunit/test_output/ seem to
have any KTAP metadata / attributes, so we probably should test that
better.
