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% )

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