perf sort: Align cpu column to right

Since cpu number is a natural number, it'd be more appropriate
aligning it to right.

Before:

  # Overhead  CPU      Command:  Pid          Shared Object
  # ........  ...  .................  .....................
  #
       8.91%  8    gnome-shell: 1497  perf-1497.map
       8.90%  7    gnome-shell: 1497  perf-1497.map
       8.86%  9    gnome-shell: 1497  perf-1497.map
       8.83%  6    gnome-shell: 1497  perf-1497.map
       8.81%  10   gnome-shell: 1497  perf-1497.map
       7.44%  5    gnome-shell: 1497  perf-1497.map
       6.20%  3    gnome-shell: 1497  perf-1497.map
       5.10%  0    gnome-shell: 1497  perf-1497.map

After:

  # Overhead  CPU      Command:  Pid          Shared Object
  # ........  ...  .................  .....................

       8.91%    8  gnome-shell: 1497  perf-1497.map

       8.81%   10  gnome-shell: 1497  perf-1497.map
       7.44%    5  gnome-shell: 1497  perf-1497.map
       6.20%    3  gnome-shell: 1497  perf-1497.map
       5.10%    0  gnome-shell: 1497  perf-1497.map
