perf stat: Fix printout vertical alignment

Before:

|
| Performance counter stats for '/home/mingo/hackbench 20' (5 runs):
|
| 71,321,607 instructions:u # 0.42 insns per cycle ( +- 0.00% )
| 168,040,009 cycles:u # 0.000 GHz ( +- 0.81% )
|
| 1.468002368 seconds time elapsed ( +- 1.33% )
|

After:

|
| Performance counter stats for '/home/mingo/hackbench 20' (5 runs):
|
| 71,321,607 instructions:u # 0.42 insns per cycle ( +- 0.00% )
| 168,040,009 cycles:u # 0.000 GHz ( +- 0.81% )
|
| 1.468002368 seconds time elapsed ( +- 1.33% )
|

The last column (stddev noise) is properly aligned, vertically.
