trace/sched: add rq utilization signal for WALT 



It is useful to be able to check current capacity against rq utilization
signal generated by WALT (to check how a cpufreq governor is behaving
for example).

Add rq utilization signal (same scale as capacity) to the walt_update_
task_ravg tracepoint.
