Describe the bug

When ssl-cert-file is not set, Lix tries /etc/ssl/certs/ca-certificates.crt and then /nix/var/nix/profiles/default/etc/ssl/certs/ca-bundle.crt. The /etc path is where Linux distros (such as NixOS) place certs. If macOS has a broken symlink at that path, Lix will use that symlink and SSL certs will break. This can happen when uninstalling nix-darwin and doing a fresh Lix install.

Lix should check the /etc/ssl/certs/ca-certificates.crt path to make sure it's not a broken symlink before using it.

> nix eval --impure -E 'builtins.fetchurl { url = "https://example.com"; }'
error:
       … while calling the 'fetchurl' builtin
         at «string»:1:1:
            1| builtins.fetchurl { url = "https://example.com"; }
             | ^

       error: unable to download 'https://example.com': Problem with the SSL CA cert (path? access rights?) (77)
