[PATCH 11/11] perf stat: Add missing separator in the CSV header

[Namhyung Kim <namhyung@kernel.org>]

It should have a comma after 'cpus' for socket and die aggregation mode.
The output of the following command shows the issue.

  $ sudo perf stat -a --per-socket -x, --metric-only -I1 true

Before:
                  +--- here
