Add an 'update-device-filter' Makefile target.

This can be (manually) used as follows to update the list of USB
VIDs/PIDs in device_filter.xml (based on the latest git version of the
libsigrok udev rules file, downloaded via wget):

  $ make update-device-filter > device_filter.xml

This fixes parts of bug #665.
