scripts: generate_rust_analyzer: Add ffi crate

commit 05a2b00 upstream.

Commit d072acd ("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.
