pkgs/misc/cups/drivers: add brother mfcl3770cdw

This adds the printer driver for the Brother MFCL3770CDW.
It combines the cups-wrapper and the driver in one file which allows
sharing common variables and making it less error-prone than the other
Brother drivers in repository.

I volunteer for maintaining this one as long as I've got the model
around.
