nix: update dependencies for brick 2.1

[lucc]

Fix #512

This still fails because of missing dependencies. Feel free to add more commits, I don't know how much time I have in the following days.

From the brick changelog:

• Added dependency on vty-crossplatform.
• Migrated from unix dependency to unix-compat.

So we should probably also package the missing vty-crossplatform and vty-unix from the build og:

So it seems the only way I can update your pull request is by creating a new pull request :-[

So I created: #514 feel free to cherry pick from there or we merged that instead. Up to you. Basically the gist is that it needed overwrites added for vty-unix and vty-crossplatform, as well as a cabal2nix update for brick.nix and vty adding the dependencies.

#514 was merged. Closing this PR. Thanks!
