print-camera-list: print udevrules for usbdiskdirect port devices

Add support for printing udev rules for usbdiskdirect port cameras
(such as the st2205). Note that the udev rule applies to the /dev/sdx
node instead of to the /dev/usb/.... one, as that is the one which needs
to get its acl's set properly to allow users access.
