Athira Rajeev 232b82d201 perf test: Update event group check for support of uncore event 
The event group test checks group creation for combinations of hw, sw
and uncore PMU events. Some of the uncore pmus may require additional
permission to access the counters.

For example, in case of hv_24x7, partition need to have permissions to
access hv_24x7 pmu counters. If not, event_open will fail. Hence add a
sanity check to see if event_open succeeds before proceeding with the
test.

Fixes: 9d9b22beda ("perf test: Add event group test for events in multiple PMUs")
