[NEW PORT] print/brlaser: Brother laser printer driver

brlaser is a CUPS driver for Brother laser printers.

Although most Brother printers support a standard printer language such
as PCL or PostScript, not all do. If you have a monochrome Brother laser
printer (or multi-function device) and the other open source drivers
don't work, this one might help.
