perf metric: Fix metric_leader
Multiple events may have a metric_leader to aggregate into. This happens for uncore events where, for example, uncore_imc is expanded into uncore_imc_0, uncore_imc_1, etc. Such events all have the same metric_id and should aggregate into the first event. The change introducing metric_ids had a bug where the metric_id was compared to itself, creating an always true condition. Correct this by comparing the event in the metric_evlist and the metric_leader.
