Bintray repository is no longer needed

LBRY SDK is now hosted on JCenter, which is already available out-of-the-box on Android Studio. The Bintray url is no longer reguired. When building LBRY on F-Droid, I have to remove this line on the build YAML script and it is building correctly.

On my local machine, it builds after commenting it.
