beamPackages.mixRelease: symlink mixFodDeps with MIX_DEPS_PATH

[Prince213]

The build is normally done in $TMPDIR/build¹, so ../deps is the same as $MIX_DEPS_PATH. But this doesn't hold for nix develop, where build is generally not in $TMPDIR, which will cause the symlink to be invalid. We now use $MIX_DEPS_PATH directly which will always be valid.

Things done

• Built on platform:
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • NixOS tests in nixos/tests.
  • Package tests at passthru.tests.
  • Tests in lib/tests or pkgs/test for functions and "core" functionality.
• Ran nixpkgs-review on this PR. See nixpkgs-review usage.
• Tested basic functionality of all binary files, usually in ./result/bin/.
• Nixpkgs Release Notes
  • Package update: when the change is major or breaking.
• NixOS Release Notes
  • Module addition: when adding a new NixOS module.
  • Module update: when the change is significant.
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other READMEs.

[Prince213]

The failures seem to be unrelated.

Not sure the value in running with the MacOS sandbox in that action, since Hydra doesn't use the sandbox either and it has known issues.
