fix(nix/writers/rust): remove args override r/2594

We can be closed world, so let’s restrict the arguments to the subset
we need for now.

The existing override was wrong, in that `// args` would use the
arguments we already added, again. So instead of deliberating about
how to make this work right in all cases, we don’t need it, we trim
it.
