pgsql: Relax overly strict sanity check for upgraded ancient databases

Relax overly strict sanity check for upgraded ancient databases

Commit 4800f16a7ad0 added some sanity checks to ensure we don't
accidentally corrupt data, but in one of them we failed to consider the
effects of a database upgraded from 9.2 or earlier, where a tuple
exclusively locked prior to the upgrade has a slightly different bit
pattern.  Fix that by using the macro that we fixed in commit
74ebba84aeb6 for similar situations.

Andres suspects that this bug may have wider ranging consequences, but I
couldn't find anything.
