perf top: Set target.system_wide
Check if neither of --pid, --tid or --uid was specified and if so, set
system_wide appropriately.
Namhyung's patch would make using any of the above target specifiers
emit a warning in perf_target__validate, since it would see
target.system_wide set and one of the others as well.
So set system_wide after validation.
