Correction for Brother BR-Script PPD files

For the PPD list entries we do not consider the ModelName if it
contains "BR-Script", as in PPD files for Brother BR-Script printers
we want to have the Product entry, as this is most probably what the
printer reports as device ID (there is no explicit device ID entry in
the PPD file).
