Android: generates JNI bindings for constructors in system classes.
This allows to simplify some places such as surface_texture_bridge. BUG= TEST= Review URL: https://chromiumcodereview.appspot.com/10968009 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@158249 0039d316-1c4b-4281-b951-d872f2087c98
