Bug#819074: point gradle to plugins

[Hans-Christoph Steiner]

Package: android-platform-tools-base
Version: 1.5.0-1
Severity: wishlist

This package includes a couple of gradle plugins, i.e. the Android
gradle plugins.  This package, a new package, or maybe even the
android-sdk package, should have the proper setup so that gradle can
automatically find those plugins.
