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 a4b8cfcabb1d ("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 to get the data. And the added perf bench
workload in 'perf all metric test case' will not run for hv-24x7 without
-a option.
Fix this issue by adding system wide check for perf bench workload.
Result with the patch changes in powerpc:
92: perf all metrics test : Ok

Tested the patch on powerpc machine, perf metrics test works fine.
91: perf all metrics test : Ok
