pgsql: Update pg_upgrade test for reg* to include regrole and regnamesp

Update pg_upgrade test for reg* to include regrole and regnamespace.

When the regrole (0c90f6769) and regnamespace (cb9fa802b) types were
added in 9.5, pg_upgrade's check for reg* types wasn't updated. While
regrole currently is safe, regnamespace is not.

It seems unlikely that anybody uses regnamespace inside catalog tables
across a pg_upgrade, but the tests should be correct nevertheless.

While at it, reorder the types checked in the query to be
alphabetical. Otherwise it's annoying to compare existing and tested
for types.
