yocto-project-qs: Updated "Building an Image" example to use Git repo

Fixes [YOCTO #5368]

Partially addresses this issue, which is removal of examples that
use a poky tarball.  I changed the example so that it clones the
upstream poky repo and then checks out a local branch named for
the most recent release.
