Don't lint names of #[no_mangle] extern fns [Rust doesn't run the `non_snake_case_name` lint on `extern fn`s with the `#[no_mangle]` attribute](rust-lang#44966). The conditions are: - The function must be `extern` and have a `#[no_mangle]` attribute. - The function's ABI must not be explicitly set to "Rust". This PR replicates that logic here.
