Incorrect use of `deprecated` attribute

[estebank]

rust-lang/rust#56896 is making the correct use of deprecated mandatory in rustc. We can't apply this as a hard error due to the following use in bindgen:

This is fixed in trunk a while ago already, so IIUC what needs to happen is to update bindgen on the wild.

Let me know if I misunderstood. I'm happy to help unblock people if they cannot update to newer versions for any particular reason.
