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
