nvidia-docker: init at 2.0.3

nvidia_x11 and persistenced were modified to provide binaries which can be
mounted inside a docker-container to be executed there.

most ldconfig-based discovery of bundled nvidia libraries is patched out

ldconfig itself is patched to be able to deal with patchelf'ed libraries
