perf stat: Fix uncore aggregation number
Follow up:
lore.kernel.org/CAP-5=fVDF4-qYL1Lm7efgiHk7X=_nw_nEFMBZFMcsnOOJgX4Kg@mail.gmail.com/
The patch adds unit aggregation during evsel merge the aggregated uncore
counters. Change the name of the column to `ctrs` and `counters` for
json mode.
Tested on a 2-socket machine with SNC3, uncore_imc_[0-11] and
cpumask="0,120"
Before:
perf stat -e clockticks -I 1000 --per-socket
# time socket cpus counts unit events
1.001085024 S0 1 9615386315 clockticks
1.001085024 S1 1 9614287448 clockticks
perf stat -e clockticks -I 1000 --per-node
# time node cpus counts unit events
