Update the patching flake to use the devbox flake (added in 37c36a1b) instead of copying the binary manually.
It uses the flakeref "github:jetify-com/devbox/" + build.Version to get the same version of Devbox that's currently running.
For dev builds, it attempts to find the devbox source and use the local flake instead.
When Devbox needs to patch a package, it generates a flake that calls devbox patch as its builder. Because flake builds are sandboxed, we need a way of getting devbox into the Nix store.
Previously, we were just copying the currently running devbox executable into the Nix store and using that. However, Devbox isn't actually a static binary (we don't build with CGO_ENABLED=0). This causes devbox patch to fail because the flake is isolated from the system's linker.
