Use shared namespace for bundled app classloader

Allow bundled apps to reference platform native libraries
located in subdirectories of the default library path
(/system/lib/hw/* for example).

In addition to this bundled apps need to share native
libraries with default namespace. Added parameter to
ApplicationLoaders.createClassLoader() to do just that.
