perf tools: Ask for ID PERF_SAMPLE_ info on all PERF_RECORD_ events
So that we can use -T == --timestamp, asking for PERF_SAMPLE_TIME:
$ perf record -aT
$ perf report -D | grep PERF_RECORD_

<SNIP>
First column is the cpu and the second the timestamp.
That way we can investigate problems in the event stream.
If the new perf binary is run on an older kernel, it will disable this feature
automatically.
