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.
