Kajol Jain f9fa0778ee perf tests stat_all_metrics: Change true workload to sleep workload for system wide check 
Testcase stat_all_metrics.sh fails in powerpc:

98: perf all metrics test : FAILED!

Logs with verbose:

  [command]# ./perf test 98 -vv

   ----

Based on above logs, we could see some of the hv-24x7 metric events
fails, and logs suggest to run the metric event with -a option.  This
change happened after the commit a4b8cfcabb ("perf stat: Delay
metric parsing"), which delayed the metric parsing phase and now before
metric parsing phase perf tool identifies, whether target is system-wide
or not. With this change, perf_event_open will fails with workload
monitoring for uncore events as expected.

The perf all metric test case fails as some of the hv-24x7 metric events
may need bigger workload with system wide monitoring to get the data.
Fix this issue by changing current system wide check from true workload
to sleep 0.01 workload.

Result with the patch changes in powerpc:

  98: perf all metrics test : Ok

Fixes: a4b8cfcabb ("perf stat: Delay metric parsing")
