Improve stability of test with vacuum_truncate in reloptions.sql
This test has been using a simple VACUUM with pg_relation_size() to
check if a relation gets physically truncated or not, but forgot the
fact that some concurrent activity, like checkpoint buffer writes, could
cause some pages to be skipped. The second test enabling
vacuum_truncate could fail, seeing a non-empty relation. The first test
would not have failed, but could finish by testing a behavior different
than the one aimed for. Both tests gain a FREEZE option, to make the
vacuums more aggressive and prevent page skips.
This is similar to the issues fixed in c2dc1a7.
