Migrate files to embedder.

 package com.google.dartndk;
 
 import java.io.File;
 import java.io.FileOutputStream;
 import java.io.InputStream;
 import java.io.IOException;
 import java.io.OutputStream;

 import android.util.Log;
 
 public class DummyActivity extends NativeActivity {
   static {
     System.loadLibrary("android_embedder");
-    System.loadLibrary("DartNDK");

I don't think we need to worry about this right now, but IIRC we should be able
to get rid of this static initializer; we needed it because we were loading more
than one native library. The dependency can instead be in one of the xml files.

I actually tried to get rid of this and ran into a problem loading
android_embedder from the manifest.  I've added a TODO to try to figure this
out.
