If no KTAP header is found in the kernel output (e.g., because the kernel crashed before the KUnit executor was run), it's very useful to re-run the test with --raw_output=all, as that will show any error output (such as a stacktrace, log message, BUG, etc). This is not particularly intuitive, however, as --raw_output=all is not well known. Add an extra log line to advertise --raw_output=all in this case, as it's a terrible user experience to just get "Did any KUnit tests run?"
