perf stat report: Allow to override aggr_mode
Allowing to override record aggr_mode. It's possible to use perf stat
like:
$ perf stat report -A
$ perf stat report --per-core
$ perf stat report --per-socket
To customize the recorded aggregate mode regardless what was used during
the stat record command.

[ Renamed 'stat' parameter to 'st' to fix 'already defined' build error with older distros (e.g. RHEL6.7) ]
