Jade Lovelace 29f5ce07db fix: flakes now obey --eval-system
This required changing an excessive number of places since flakes code
is a delicious bowl of copy pasta.

I didn't change all of the usage sites since some of them run things on
the local machine and you actually want it to be the real system there.

Nevertheless, we probably should have the daemon do something much
different when it receives a `system` setting:

Flakes follow `--eval-system` where it makes sense

Most flake commands now follow --eval-system when choosing attributes to build/evaluate/etc.

The exceptions are commands that actually run something on the local machine:

  • nix develop
  • nix run
  • nix upgrade-nix
  • nix fmt
  • nix bundle

This is not a principled approach to cross compilation or anything, flakes still impede rather than support cross compilation, but this unbreaks many remote build use cases.
