kbd: Patch in support for the Neo keyboard layout.

This adds support for the Neo keyboard layout (http://neo-layout.org/

, a
layout optimized for the German language) for the native Linux console.

It also adds build dependencies on autotools and friends, because we
need to recreate the automake config in order to include a new keyboard
layout directory.
