[notify] cups: allow printer access via libusb or the usblp kernel module

the "usb" backend can currently be either compiled to access the
printers through the "usblp" kernel module (/dev/usb/lp*) or through
libusb (low-level USB), but one cannot have one backend which uses both
access methods.
The applied patch from Till Kamppeter fixes this disappointing behaviour.
