tests: test_dfu.py: Add example udev rule for host_usb_dev_node
If one does not already have a rule to create a custom device node when
a given device enumerates it can be useful to have udev create a
bus path based node to the entry in /dev/bus/usb that was just
enumerated. Given that DFU itself does not require a /dev entry it is a
good idea to provide a rule that will generate one.
