As noted elsewhere on the thread, these errors means that kunit.py
can't parse the KTAP output coming from the kernel.
There shouldn't be any recent changes in either the python-side parser
or the kernel-side output logic.

So I can't think of a kunit-specific change that would trigger this.
There could be some other issue causing output mangling.

We'd want to look at what output the UML kernel produces (stored in
.kunit/test.log, or visible via kunit.py run --raw_output).
