[PATCH v3 16/16] perf record: Retirement latency cleanup in evsel__config

[Ian Rogers]

Perf record will fail with retirement latency events as the open
doesn't do a perf_event_open system call. Use evsel__config to set up
such events for recording by removing the flag and enabling sample
weights - the sample weights containing the retirement latency.
