meta-quanta: conf bugfix: layer

Fix the quanta layer to be named "quanta-layer" to conform to
expectations.  Also add missing boilerplate code to add recipes from
this layer.  There are currently no recipes in this layer outside of
within a machine specification, but the change will prevent future bugs.
