cloudflare-dns: its tools and provisioner run in the node's runtime (hq ADR 0198)

The mesh-cloudflare-dns container goes with its Dockerfile, build bases, bus credential and state directory. MESH_RECEIVES now names the grants directory itself; the container's value pointed at a path nothing was mounted on.
