perf test: Add automated tests for pmu sysfs translated events

Browse Source 
Add automated tests for all events found under PMU/events
directory. Tested events are in the 'cpu/event=xxx/u' format,
where 'xxx' is substituted by every event found.

The 'event=xxx' term is translated to the cpu specific term.
We only check that the event is created (not the real config
numbers) and that the modifier is properly set.
