[PATCH] rust: bindings: disable more clippy warnings

[PATCH] rust: bindings: disable more clippy warnings

[Paolo Bonzini]

The clippy::complexity category includes manual_div_ceil, which triggers
with e.g. bindgen 0.73.2.  It is not really relevant to automatically
generated code so drop it from all bindgen crates, but keep it
enabled on purpose for other code.
