    sort: Fix message catalogue usage
    
    - Check that catopen() succeeded before calling catclose().  musl will
      crash in the latter if the catalogue descriptor is -1.
    - Keep the message catalogue open for most of sort(1)'s actual
      operation.
    - Don't use catgets(3) to print error messages if catopen(3) had failed.
