fix(tvix/glue): reject unknown attrset args for fetch builtins r/8315
This now uses UnexpectedArgumentBuiltin in case builtins.fetchurl or
builtins.fetchTarball are called with the wrong arguments:
```
note: while evaluating this Nix code
--> [code]:1:1
|
1 | builtins.readDir (builtins.fetchTarball { url = "https://git"; hash = "sha1-NKNeU1csW5YJ4lCeWH3Z/apppNU=";})
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
error[E040]: Unexpected agrument `"hash"` passed to builtin
--> [code]:1:19
|
1 | builtins.readDir (builtins.fetchTarball { url = "https://git"; hash = "sha1-NKNeU1csW5YJ4lCeWH3Z/apppNU=";})
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ while calling this builtin
```
