Rollup merge of #125104 - Oneirical:test6, r=jieyouxu

Migrate `run-make/no-cdylib-as-rdylib` to `rmake`

Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).

> "the test will fail if the cdylib is picked, because it doesn't export any rust symbols"

Is that true? Is there a way to verify?

I suggest maybe extending the test with: (after cleaning the directory)

```rust
    rustc()
        .input("bar.rs")
        .crate_type("cdylib")
        .run();
    rustc()
        .input("foo.rs")
        .prefer_dynamic()
        .run();
    fail();
```

to make sure we're actually testing something here.
