Add back the SUPL network setup timeout.

The network request timeout functionality in the ConnectivityManager
class was non functional. When it was addressed, the timeout that was
in the GnssLocationProvider class was removed as it was referring to
a constant in the ConnectivtyManager that was deleted. See b/35354391
for details.
