perf stat: Align the output for interval aggregation mode
There is a slight misalignment in -A -I output.
For example:
 # perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000
 #           time CPU                    counts unit events
      1.000440863 CPU0               1,068,388      cpu/event=cpu-cycles/
      1.000440863 CPU1                 875,954      cpu/event=cpu-cycles/
      1.000440863 CPU2               3,072,538      cpu/event=cpu-cycles/
      1.000440863 CPU3               4,026,870      cpu/event=cpu-cycles/
      1.000440863 CPU4               5,919,630      cpu/event=cpu-cycles/
      1.000440863 CPU5               2,714,260      cpu/event=cpu-cycles/
      1.000440863 CPU6               2,219,240      cpu/event=cpu-cycles/
      1.000440863 CPU7               1,299,232      cpu/event=cpu-cycles/
The value of counts is not aligned with the column "counts" and
the event name is not aligned with the column "events".
With this patch, the output is,
 # perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000
 #           time CPU                    counts unit events
      1.000423009 CPU0                  997,421      cpu/event=cpu-cycles/
      1.000423009 CPU1                1,422,042      cpu/event=cpu-cycles/
      1.000423009 CPU2                  484,651      cpu/event=cpu-cycles/
      1.000423009 CPU3                  525,791      cpu/event=cpu-cycles/
      1.000423009 CPU4                1,370,100      cpu/event=cpu-cycles/
      1.000423009 CPU5                  442,072      cpu/event=cpu-cycles/
      1.000423009 CPU6                  205,643      cpu/event=cpu-cycles/
      1.000423009 CPU7                1,302,250      cpu/event=cpu-cycles/
Now output is aligned.
