Jiri Olsa 82ce75d933 perf tests: Add event parsing test for '*:*' tracepoints 
Adding event parsing test for '*:*' tracepoints. Checking the count
matches all the tracepoints available plus current standard tracepoint
perf_event_attr check.

This test exposes warnings from traceevent lib about not being able to
parse some tracepoints' format data. Exposing these messages in the
automated test suite will probably speed up the fix ;-)
