sched_ule: Enable preemption of curthread in the load balancer
The load balancer executes from statclock and periodically tries to move
threads among CPUs in order to balance load. It may move a thread to
the current CPU (the loader balancer always runs on CPU 0). When it
does so, it may need to schedule preemption of the interrupted thread.
Use sched_setpreempt() to do so, same as sched_add().
