Subject: [PATCH] scripts: generate_rust_analyzer: Add ffi crate

Commit d072acda4862 ("rust: use custom FFI integer types") did not
update rust-analyzer to include the new crate.

To enable rust-analyzer support for these custom ffi types, add the
`ffi` crate as a dependency to the `bindings`, `uapi` and `kernel`
crates, which all directly depend on it.
