The commit 6f06ad7df1
fixed a way to load native library for NativeActivity
by using classloader logic to find the library; which
also fixed the problem of native activity not working
when library is supposed to be opened directly from
the apk.
As a side effect it introduced regression - apps without
java code did not have correctly initialized classloader.
This change fixes this by constructing classloader with
empty dexpath but valid nativeLibrarySearchPath.
