fetch: nicer infinite recursion errors
- This change applies to builtins.fetchurl and builtins.fetchTarball - PoC: `let x = builtins.fetchurl x; in x` - Before: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered ``` - After: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered at /data/github/kamadorueda/nix/test.nix:1:9: 1| let x = builtins.fetchurl x; in x | ^ ``` Mentions: #3505
