make raw USB printer devices accessible for lp

Browse Source 
Starting from version 1.4, cups now uses libusb and printer USB devices instead
of the usblp generated /dev/usb/lpX ones. In order to not require the cups USB
backend to run as root now, change raw USB printer devices to be root:lp 0660,
similar to usblpX devices.

This might also enable the hplip backend to not run as root, since this has
always used raw device nodes.
