perf session: Remove last reference to hists struct

Now perf_session doesn't require that the evsels in its evlist are hists
containing ones.

Tools that are hists based and want to do per evsel events_stats
updates, if at some point this turns into a necessity, should do it in
the tool specific code, keeping the session class hists agnostic.
