refactor(tvix): assemble cragoDeps outputHashes from Cargo.nix

Browse source 
We already have these hashes accessible in the Cargo.nix file created
by cargo2nix, so there's no need to also manually maintain them here.

It removes one potential footgun I ran into while updating wu-manber to
a different rev, without updating it here.
