hello-mod: add a module for testing module.bbclass

The following patch creates a hello-mod recipe for building a trivial
out-of-tree kernel module, hello-mod.ko. This demonstrates the hostprogs
build modifications added to module.bbclass. When loaded and unloaded,
the module prints a simple string to the console to demonstrate it was
compiled correctly.

Tested on qemux86 poky-image-sato and beagleboard poky-image-minimal
(after adding hello-mod to the images).
