perf test stat: Update test expectations and events

Browse Source 
test_stat_record_report and test_stat_record_script used default
output which triggers a bug when sending metrics. As this isn't
relevant to the test switch to using named software events.

Update the match in test_hybrid as the cycles event is now cpu-cycles
to workaround potential ARM issues.
