rust: Ignore preserve-most functions 

commit bad098d768 upstream.

Neither bindgen nor Rust know about the preserve-most calling
convention, and Clang describes it as unstable. Since we aren't using
functions with this calling convention from Rust, blocklist them.

These functions are only added to the build when list hardening is
enabled, which is likely why others didn't notice this yet.
