Remove pg_constraint.conincluding
This column was added in commit 8224de4f42cc ("Indexes with INCLUDE
columns and their support in B-tree") to ease writing the ruleutils.c
supporting code for that feature, but it turns out to be unnecessary --
we can do the same thing with just one more syscache lookup.
Even the documentation for the new column being removed in this commit
is awkward.
