fix(android): improve reliability of fused location lib detection

- The Ti.Geolocation APIs would never work if "play-services-base" lib was included, but "play-services-location" lib was missing.
- Now checking for classes in both libs before proceeding to use Fused Location feature.
- This can happen in Titanium 9.0.0 now that app devs can set up their own custom "build.gradle" file which specifies its own lib dependencies.
