perf report: Introduce --socket-filter option
Introduce --socket-filter option for 'perf report' to only show entries
for a processor socket that match this filter.
$ perf report --socket-filter 1 --stdio
# To display the perf.data header info, please use --header/--header-only options.
#
# Total Lost Samples: 0
#
# Samples: 752 of event 'cycles'
# Event count (approx.): 350995599
# Processor Socket: 1
