Subject: [PATCH 1/2] kunit: tool: add parsing of test attributes

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 log.

This could be changed to do the opposite if preferred.
