psql \dX: reference regclass with "pg_catalog." prefix

Déjà vu of commit fc40ba1296a7, for another backslash command.
Strictly speaking this isn't a bug, but since all references to catalog
objects are schema-qualified, we might as well be consistent.  The
omission first appeared in commit ad600bba0422 and replicated in
a4d75c86bf15; backpatch to 14.
