nohz: Rename ts->idle_tick to ts->last_tick
Now that idle and nohz logics are going to be independant each others,
ts->idle_tick becomes too much a biased name to describe the field that
saves the last scheduled tick on top of which we re-calculate the next
tick to schedule when the timer is restarted.
We want to reuse this even to stop the tick outside idle cases. So let's
rename it to some more generic name: ts->last_tick.
This changes a bit the timer list stat export so we need to increase its
version.
