perf tools: Handle PERF_RECORD_HEADER_EVENT_TYPE properly
We removed event types from data file in following commits:
6065210 perf tools: Remove event types framework completely
44b3c57 perf tools: Remove event types from perf data file
We no longer need this information, because we can get it directly from
tracepoints.
But we still need to handle PERF_RECORD_HEADER_EVENT_TYPE event for the
sake of old perf data files created in pipe mode like:
$ perf.3.4 record -o - foo >perf.data
$ perf.312 report -i - < perf.data
