rust: start supporting several bindgen versions
With both the workaround for `bindgen` 0.69.0 and the warning about 0.66.0 and 0.66.1 in place, start supporting several `bindgen` versions, like it was done for the Rust compiler in a previous patch. All other versions, including the latest 0.69.4, build without errors. The `bindgen` project, like Rust, has also agreed to have the kernel in their CI [1] -- thanks! This should help both projects: `bindgen` will be able to detect early issues like those mentioned above, and the kernel will be very likely build with new releases (at least for the basic configuration being tested).
