[PATCH 05/13] perf sort: Set flag stating if the "socket" key is being used

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Because it will require that we read the current machine CPU topology
map when the tool is not processing a perf.data file, from where it
would obtain that map.

Other tools may want to do some other initialization in such case.

We need to have a better way to figure out if a given sort key is being
used, perhaps a bitmap, but that is left for another patch.
