[PATCH 8/8] perf tools: Enlarge pid sort entry size

[Jiri Olsa]

The pid sort entry currently aligns pids with 5 digits,
which is not enough for current 4 million pids limit.

This leads to unaligned ':' header-data output when
we display 7 digits pid:

  # Children      Self  Symbol                    Pid:Command
  # ........  ........  ......................  .....................
  #
       0.12%     0.12%  [.] 0x0000000000147e0f  2052894:krava
  ...

Adding 2 more digit to properly align the pid limit:

  # Children      Self  Symbol                      Pid:Command
  # ........  ........  ......................  .......................
  #
       0.12%     0.12%  [.] 0x0000000000147e0f  2052894:krava
