xpp_fxloader: adapt to newer kernels

This commit prepares xpp_fxloader to get hotplug envirnment from newer kernel
versions:
* DEVICE will eventually be replaced with DEVNAME. Accept both (and look
  at DEVNAME first).
* If we get DEVICE, we'll probably get an invalid path based at
  /proc/bus/usb . Fix it to use /dev/bus/usb .
* While we're at it, allow using PRODUCT from the envirnment instead of
  from the command-line.

This should allow fixing udev rules but will also work with existing
rules in DAHDI-linux (for systems where they are valid).
