ktest: Add option REBOOT_SUCCESS_LINE to stop waiting after a reboot
When ktest.pl reboots, it will usuall wait SLEEP_TIME seconds of idle console before starting the next test. By setting the REBOOT_SUCCESS_LINE, ktest will not wait SLEEP_TIME when it detects the line while rebooting to a new kernel. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
