Fix further fallout from EXPLAIN ANALYZE BUFFERS change

Browse Source 
c2a4078eb adjusted EXPLAIN ANALYZE to default the BUFFERS to ON.  This
(hopefully) fixes the last remaining issue with regression test failures
with -D RELCACHE_FORCE_RELEASE -D CATCACHE_FORCE_RELEASE builds, where
the planner accesses more buffers due to the cold caches.
