perf tools: Add support for PERF_SAMPLE_IDENTIFIER
Enable parsing of samples with sample format bit
PERF_SAMPLE_IDENTIFIER.
In addition, if the kernel supports it, prefer it to selecting
PERF_SAMPLE_ID thereby allowing non-matching sample types.

perf_evlist__event2evsel() is failing. From what I can see the problem
is that evlist->heads is not getting populated. This command does not
read/write files but processes events as they come in. I have another
similar command that is also breaking for the same reason.
