Bug 4925: Remove Smithsonian as a delivered z39.50 target

Bug 4925: Remove Smithsonian as a delivered z39.50 target

Removes the Smithsonian as a target installed with the
sample data during installation.

Also adds the newer LOC authority targets to files where
they were missing.

To test:
- Verify the Smithsonian has been removed from all
  translated installers
- Verify the files are still valid SQL and install
  correctly

NOTE: There was tiny scope creep which included ensuring
      there were two Authority z39.50 servers as well.
      Text files properly reflect the removal.
      SQL 'source' of SQL files worked properly.
      Was able to Z39.50 search for all of the 'en'.
