perf stat: Add noise output for csv mode
Previously, when you want perf-stat to output the statistics in
csv mode, no information of the noise will be printed out.
For example right now we output this --repeat information:
./perf stat -r3 -x, sleep 1
1.164789,task-clock
8,context-switches
0,CPU-migrations
219,page-faults
3337800,cycles
With this patch, the output will be appended with an additional
entry for the noise value:
./perf stat -r3 -x, sleep 1
1.164789,task-clock,3.75%
8,context-switches,75.00%
0,CPU-migrations,100.00%
219,page-faults,0.00%
3337800,cycles,3.36%
