Yafang Shao ed7b564cfd sched/rt: Support sched_stat_runtime tracepoint for RT sched class
The runtime of a RT task has already been there, so we only need to
add a tracepoint.

One difference between fair task and RT task is that there is no vruntime
in RT task. To reuse the sched_stat_runtime tracepoint, '0' is passed as
vruntime for RT task.

The output of this tracepoint for RT task as follows,
          stress-9748    [039] d.h.   113.519352: sched_stat_runtime: comm=stress pid=9748 runtime=997573 [ns] vruntime=0 [ns]
          stress-9748    [039] d.h.   113.520352: sched_stat_runtime: comm=stress pid=9748 runtime=997627 [ns] vruntime=0 [ns]
          stress-9748    [039] d.h.   113.521352: sched_stat_runtime: comm=stress pid=9748 runtime=998203 [ns] vruntime=0 [ns]
