rust: work around `bindgen` 0.69.0 issue
`bindgen` 0.69.0 contains a bug: `--version` does not work without providing a header [1]: error: the following required arguments were not provided: <HEADER> Usage: bindgen <FLAGS> <OPTIONS> <HEADER> -- <CLANG_ARGS>... Thus, in preparation for supporting several `bindgen` versions, work around the issue by passing a dummy argument. Include a comment so that we can remove the workaround in the future.
