aufs-util: Add AUFS Utils for ver 3> kernels.

* Must have AUFS headers in the kernel tree and kernel must have AUFS support built.
* Recipe contains a header hack I don't like (see .bb). Need to find a clean OE way to manage this.
* TODO: Add build time checks for headers and abort cleanly if they do not exist with a good error message.
