sched/dl: Support sched_stat_runtime tracepoint for deadline sched class
The runtime of a DL task has already been there, so we only need to add a tracepoint.
One difference between fair task and DL task is that there is no vruntime in dl task. To reuse the sched_stat_runtime tracepoint, '0' is passed as vruntime for DL task.
The output of this tracepoint for DL task as follows, top-36462 [047] d.h. 6083.452103: sched_stat_runtime: comm=top pid=36462 runtime=409898 [ns] vruntime=0 [ns]
