perf top: Create the evlist sooner
This is a preparation to support dynamic sort keys for tracepoint events. Dynamic sort keys can be created for specific fields in trace events so it needs the event information, so we need to pass the evlist to the sort routines, create it sooner so that the next patch can do that.
