Tweak sanity_check regression test to display more tables (viz, those

without indexes) but not to display temp tables.  It's a bit hard to
credit that sanity_check could get through a database-wide VACUUM
while the preceding create_index test is still trying to clean up
its temp tables ... but I see no other explanation for the current
failure report from buildfarm member sponge.
