Replace the standalone connectcore-demo-example-webkit recipe with
a bbappend extending the main demo recipe. This is in preparation for
adding support for chromium-based connectcore demo.
While on it, merge the .inc file into the main recipe as there is only a
consumer of that inc file. Also minor cosmetic fixes to make the recipe
more Yoct-ish.
