Fix task and thread collection frequency
sched_tick is incremented only once per second, not once per tick.
* kern/task.c (consider_task_collect): Divide task_collect_max_rate by
(hz / 1) to get a number of scheduler ticks.
* kern/thread.c (consider_thread_collect): Divide thread_collect_max_rate by
(hz / 1) to get a number of scheduler ticks.
