ktest: Monitor kernel while running of user tests
Record the console of tests to both the console and the log. Also, record the bug reports afte the test has completed. Currently, if a kernel bug happens while running the userland test, the test stops and will not record the kernel bug. This makes it difficult to solve what happened.
