Android Launcher: Fix ClassLoaderUtil's JNI lib-path determination, use ApplicationInfo's nativeLibraryDir (API level 9).

On Android > 4.0.3 (maybe even earlier), w/ a split filesystem (internal and SDCARD)
the JNI libs maybe stored at a different location than it's data path.
ApplicationInfo's nativeLibraryDir properly determines the JNI storage location, hence use it.

Prev. code also derived JNI lib path by the launcher's ApplicationInfo's nativeLibraryDir,
which might be different than the user package's nativeLibraryDir.
This is especially true, since the launcher may not hold any native libraries.
