perf annotate: Process tracing data in pipe mode
'perf annotate' was missing the handler for tracing data records.
Prior to this patch we obtained "unhandled" records when piping trace
events to perf annotate (using -D option to show the dump_printf
messages in process_event_synth_tracing_data_stub):
$ perf record -o - -e block:bio_free sleep 2 | perf annotate -D --stdio
...
0x78 [0xc]: PERF_RECORD_TRACING_DATA: unhandled!
