Clean up extra dependencies added by zbus #674
Description
Zbus was added as part of #661 is merged, which brought a new set of dependencies that are newer than those in the current first party sources, specifically:
- nix
- rand
- rand_chacha
- rand_core
- winnow
I tried to update nix but it requires some refactor in apiserver, apiclient and thar-be-updates. I have not tried with all the others.
