tracing/sched: show CPU task wakes up on in trace event

While debugging the scheduler push / pull algorithm, I found
it very annoying that the sched wake up events did not show
the CPU that the task was waking on. In order to analyze the
scheduler, I needed that information.

This patch adds recording of the CPU that a task is waking up
on.
