[Nix] Update nixpkgs

Summary:
Update most of the tooling with exception of arcanist and MariaDB
which require additonal work to be compatible.

Also prune much of the C++ libraries which are no longer being used
since the C++ tunnelbroker codebase has been removed. These C++ libraires
were also a significant contributer to Nix build times.

Test Plan:

• Web, iOS, and Android dev work flow
• Run identity + tunnelbroker integration tests
