perf hists: Enlarge pid sort entry size

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
