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.
