Export SDK library names

java_library, java_import, and android_library export SDK library names
that they are using directly or indirectly via its dependencies. When
building an apk, the manifest fixer uses the SDK lib names to
automatically add <uses-library> tags.

The SDK lib names are exported to the make world via
LOCAL_EXPORT_SDK_LIBRARIES flag.
