In [1], a mechanism was proposed to create layer-specific aptly binary
repositories in addition to the existing `deb-local-binary`, to better
separate the binary dependencies of each layer.
For this new mechanism to work, new repositories must be dynamically
taken into account by `sbuild`, by adding a new `--extra-repository`
argument referring to the layer of the package being built, which is
precisely what this change does.
