This logic depends on the kernel logging a message containing 'kunit test case crashed', but there is no corresponding logic to do so.
This is likely a relic of the revision process KUnit initially went through when being upstreamed.
Delete it given 1) it's been missing for years and likely won't get implemented 2) the parser has been moving to be a more general KTAP parser, kunit-only magic like this isn't how we'd want to implement it.

This seems sensible to me, though it doesn't change a lot in practice given that the in-kernel KUnit will mark empty suites as skipped: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/...
(And I think that is probably the correct thing for it to do, as "no tests run" seems closer to skipped than to passed or failed, which are the other options KTAP gives us.)
That being said, it's definitely true that we don't want to override a "not ok" needlessly in kunit_tool, so this patch is definite improvement.
