Removed the non-test related Ant targets

The Strongback and 3rd party libraries are installed (via the Strongback CLI) into the WPILib's `user/java/lib` directory and therefore are found, used, and deployed during the WPILib's standard Ant build process.

However, WPILib's build does not support unit tests, so this file defines Ant targets related only for unit testing. Thus, a robot project that uses Strongback at runtime and has no tests need not use this Ant file.
