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.
