Those logs are the raw output from UML with KUnit installed. They are
for testing kunit_tool, the Python scripts added in this commit. One
of the things that kunit_tool does is parses the results output by
UML, extracts the KUnit data, and presents it in a user friendly
manner.

I added these logs so I could test that kunit_tool parses certain
kinds of output correctly. For example, I want to know that it parses
a test failure correctly and includes the appropriate context. So I
have a log from a unit test that failed, and I have a test (a Python
test that is also in this commit) that tests whether kunit_tool can
parse the log correctly.

Does that make sense?
