perf top: Use perf_evlist__config()

Browse Source 
Using struct perf_record_opts to specify how to configure the evsel
perf_event_attrs.

This gets top closer to record in the way it sets up evsels, with the
aim of sharing more and more to the point that both will be a single
utility.

In this direction top now uses the same callchain option parsing as
record and that brings DWARF callchains to top, something that was
already available for record.
