man pages no longer state drop_oracle_catalogue_schema.sql is safe.

The drop_oracle_catalogue_schema.sql is raw SQL and contains no
PL/SQL.  The logic to protect a LOCKED catalogue schema is
therefore gone.

Operators/admins should now use the cta-catalogue* command-line
tools instead.  These tools are safe.
