Draft: blueprints-ci: add recipe

Only deploys blueprints-ci repository as tar ball to build output, nothing else needed. CI system should then use these scripts.

Copying the files from meta-layer checkout is not so easy with bitbake recipes so use full indirection to clone the repo inside do_fetch() task when recipe is compiled.
