Use default SysTick interrupt priority.
We really don't want SysTick_Handler, which runs the task scheduler, to
run at a higher priority than SVC_Handler, which runs supposedly-atomic
operations like mutex locking and unlocking. I've seen a mutex lock/unlock
mismatch which I think is due to interrupting rt_mut_release at a
particularly inopportune moment.
