perf python: In str(evsel) use the evsel__pmu_name helper

The evsel__pmu_name helper will internally use evsel__find_pmu that
handles legacy events, extended types, etc. in determining a PMU and
will provide a better value than just trying to access the PMU's name
directly as the PMU may not have been computed.
