modem_gps.sh: Add a script to use the WWAN modem GPS



By moving the AUX BM818 antenna connector to the unmarked center position
the modem can get a GPS signal. This NOT the GNSS controlled by HKS but is
part of the WWAN modem so is bound to the modem firmware and the WWAN HKS.

# gpsd doesn't wnat to share with ModemManger so give it a fifo instead
# To get this to work you need to modify /etc/default/gpsd to
# monitor "/tmp/gps". You also need to move the AUX BM818 antenna connection
# to the center unmarked position.
