perf tools: Record events info also when :record suffix is used.



You can enable a counter's PERF_SAMPLE_RAW attribute in two
fashions:

- using the -R option (every counters get PERF_SAMPLE_RAW)
- using the :record suffix in a trace event counter name

Currently we record the events info in a trace.info file from
perf record when the former method is used but we omit it with
the latter.

Check both situations.
