[fix] Allow only installable DEVELOP_DIST in index

The package index considers may yield develop dists found on its local
search_path - sys.path by default - in addition to its index_url.

This commit discards such dists when they do not contain a setup.py
nor a pyproject.toml, as a good heuristic of whether they will be
installable or not.
