Add libjavacrypto.so to the runtime APEX

Since the lib is used with dlopen, there is no build-time dependency to
the library from anything in the runtime library. As a result, the lib
hasn't been included in the runtime APEX. Fixing this by explicitly
listing the lib name in the native_shared_libs property.
