#14039: Many unnecessary CPU wakeups per second

---------------------+-------------------------------
PowerTOP shows Tor waking up 10 times per second even when it’s doing
nothing. This is bad for power usage on a laptop because it prevents the
CPU from entering its deepest sleep states. It looks like the reason is
the default TokenBucketRefillInterval of 100 msec (#3630). Perhaps this
logic can be refactored so that `refill_timer` is only activated when
there are buckets to be refilled.
