Force some system catalog table columns to be marked NOT NULL.
In a manual pass over the catalog declaration I found a number of
columns which the boostrap automatism didn't mark NOT NULL even though
they actually were. Add BKI_FORCE_NOT_NULL markings to them.
It's usually not critical if a system table column is falsely determined
to be nullable as the code should always catch relevant cases. But it's
good to have a extra layer in place.
