PMU name is printed repeatedly for interval print, for example:
perf stat --no-merge -e 'unc_m_clockticks' -a -I 1000
# time counts unit events

For each print, the PMU name is unconditionally appended to the
counter->name.
Need to check the counter->name first. If the PMU name is already
appended, do nothing.
Committer notes:
Add and use perf_evsel->uniquified_name bool instead of doing the more
expensive strstr(event->name, pmu->name).
