build-support: fix nix-prefetch-* on macOS

Browse source 
Since nix 2.20, `nix-store --add-fixed` doesn't accept paths where the
parent directory is a symlink. On macOS, /tmp is a symlink to
/private/tmp, which causes a "'/tmp' is a symlink" error:

```
$ nix run github:nixos/nixpkgs/24.11-beta#nix-prefetch-git -- --url https://github.com/IFTTT/polo.git --rev 316aa2ac210a45a7fc400ab921831493d5dd21b8 --hash sha256

Switched to a new branch 'fetchgit'
removing `.git'...
error: path '/tmp' is a symlink
```

Avoid this by resolving /tmp to a real directory in all the prefetch scripts
