Firefox geolocation is not working with Google API

[Timur I. Davletshin]

Official build of Firefox 49 in 16.04 is not working with Google Geolocation API while Mozilla builds are able to fetch location information. Changing geo.wifi.uri from default https://www.googleapis.com/geolocation/v1/geolocate?key=%GOOGLE_API_KEY% to https://location.services.mozilla.com/v1/geolocate?key=%MOZILLA_API_KEY% will fix this problem.

I believe problem is with %GOOGLE_API_KEY%
