perf report: Make another loop for linking group hists

Now the event grouping viewing requires linking all member hists in a
group to the leader's.  Thus hists__output_resort should be called after
linking all events in evlist.

Introduce symbol_conf.event_group flag to determine whether the feature
is enabled or not.
