perf tools: Introduce new sort type "socket" for the processor socket

This patch enable perf report to sort by processor socket:

  $ perf report --stdio --sort socket,comm,dso,symbol
  # To display the perf.data header info, please use --header/--header-only options.
  #
  # Total Lost Samples: 0
  #
  # Samples: 686  of event 'cycles'
  # Event count (approx.): 349215462
  #
  # Overhead SOCKET Command Shared Object    Symbol
  # ........ ...... ....... ................ ............................
