perf record: Stop intercepting events, use postprocessing to get build-ids
We want to stream events as fast as possible to perf.data, and also in the future we want to have splice working, when no interception will be possible. Using build_id__mark_dso_hit_ops to create the list of DSOs that back MMAPs we also optimize disk usage in the build-id cache by only caching DSOs that had hits.
