[PATCH perf/core 19/22] perf: fix hists_evsel to release hists

Since hists__init doesn't set the destructor of
hists_evsel (which is an extended evsel structure),
when hists_evsel is released, the extended part of
the hists_evsel is not deleted (note that the
hists_evsel object itself is freed).

This fixes it to add a destructor for hists__evsel
and to set it up.
