Remset summary printing prints coarsening statistics in addition to remset summaries; that information is either duplicated with "Coarsening (recent)" printouts (with gc+remset=debug) at GC start or all-zeros at GC end.

Given that Remset summary printing is enabled with gc+remset=trace which covers the recent/all coarsening statistics, the coarsening statistics during remset summary are somewhat duplicate (or useless for the after-gc one).

Remove the coarsening statistics from the remset summaries.
