Zhengyu He 3ae9a34d74 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%
