Hostip geolocation provider does not return position info

While we're using geoclue-ubuntu-geoip for detecting the current position in the location QR code, we have a fallback to using geoclue-hostip for other distros that don't have geoclue-ubuntu-geoip available (e.g. Fedora).

However, when testing Hostip, it seems to return no location data at all. For the test, I just swapped providers in the QRCodeLocationGtk.py file:

    try:
        geoclue = bus.get_object(
            'org.freedesktop.Geoclue.Providers.Hostip',
            '/org/freedesktop/Geoclue/Providers/Hostip')
        print "Got Hostip geoclue provider"
    except dbus.exceptions.DBusException:
        geoclue = bus.get_object(
            'org.freedesktop.Geoclue.Providers.UbuntuGeoIP',
            '/org/freedesktop/Geoclue/Providers/UbuntuGeoIP')
        print "Got Ubuntu GeoIP geoclue provider"

And then the position_info fields related to latitude and longitude are empty.
