perf tools: Merge all perf_event_attr print functions
Currently there's 3 (that I found) different and incomplete
implementations of printing perf_event_attr.
This is quite silly. Merge the lot.
While this patch does not retain the exact form all printing that I
found is debug output and thus it should not be critical.
Also, I cannot find a single print_event_desc() caller.
