[PATCH 4/6] ktest: Reboot after each patchcheck run

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

The patches being checked may not leave the kernel in a state
that the next run will allow the new kernel to be copied to the
machine. Reboot to a known good kernel before continuing to the
next kernel to test.

Added option PATCHCHECK_SLEEP_TIME for the max time to sleep between
patchcheck reboots.
