ktest: Add check for bug or panic during reboot
Usually the target is booted into a dependable kernel when a test starts. The test will install the test kernel and reboot the box. But there may be a time that the kernel is running an unreliable kernel and the reboot may crash. Have ktest detect crashes on a reboot and force a power-cycle instead. This can usually happen if a test kernel was installed to run manual tests, but the user forgot to reboot to the known good kernel. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
