The checks in 0.6.0 did no longer work with the updated dependencies.
Updating to 0.7.0 fixes the issue.
The deps.nix file was used for the go version and is no longer required
as remarshal is now written in python.
After #16017 there were a lot
of comments saying that `nix` would be better than `JSON`
for Go packages dependency sets.
As said in https://github.com/NixOS/nixpkgs/pull/16017#issuecomment-229624046

This PR removes `libs.json` file and puts all package dependencies in
theirs `deps.json`.
