[TIMOB-26131] Android: SDK is wrongly adding core "Google Play Services" libraries as of 7.1.0

*Summary:* As of Titanium 7.1.0, the SDK is wrongly including the following JAR files to all Android app builds... * play-services-base-11.0.4.jar * play-services-basement-11.0.4.jar * play-services-location-11.0.4.jar * play-services-tasks-11.0.4.jar On a Mac, you can verify that the above libraries are wrongly being included by going to the following directory in Finder... ~/Library/Application Support/Titanium/mobilesdk/osx/7.x.x/android These 4 libraries are not supposed to be there and it's preventing us from updating the "ti.playservices" module's Google Play Services libraries to a newer version (will cause a version conflict). *Note:* Titanum's core "geolocation" code needs a reference to the above mentioned JAR files to compile, but it doesn't require the JAR files to be included. This is because our "geolocation" code will dynamically detect the existence of the Google Play Services classes via reflection... and if they don't exist, it'll fallback to using the OS' location APIs instead. So, we need to exclude the Google Play Services JARs when packaging the SDK.
