Zerocopy 0.8.32 breaks combined with `deny(non_ascii_idents)`

For security reasons we cannot allow `non-ascii-identifiers` in our codebase, and as such we apply `#![deny(non_ascii_idents)]`.

However, since upgrading to Zerocopy 0.8.32 (0.8.33 has same behavior) we are running into violations of the `non_ascii_idents` lint.

`src/main.rs`:

```rust
#![deny(non_ascii_idents)]

use zerocopy::{FromBytes, Immutable, IntoBytes, KnownLayout};

#[derive(KnownLayout, FromBytes, IntoBytes, Immutable)]
#[repr(C)]
pub struct ifaddrmsg {
pub ifa_family: u8, /* Address type */
pub ifa_prefixlen: u8, /* Prefixlength of address */
pub ifa_flags: u8, /* Address flags */
pub ifa_scope: u8, /* Address scope */
pub ifa_index: u32, /* Interface index */
}

fn main() {}
```

Cargo.toml:
```
[package]
name = "zerocopy-non-ascii-error"
version = "0.1.0"
edition = "2024"

[dependencies]
zerocopy = { version = "0.8.33", features = ["derive"] }
```

`bash`:

```bash
❯ cargo run

Traced back to this PR: https://github.com/google/zerocopy/commit/002b97de9b73c1d012ae8241780931e717965219#diff-977c29e6cf079bd7307f811df24f99633df603962785c583145eb6250b0e12daR755

There was a comment about it: https://github.com/google/zerocopy/pull/2842#discussion_r2590153675 but no mention of `non_ascii_idents`.

Could an allow be applied to those lines, just like here: https://github.com/google/zerocopy/commit/002b97de9b73c1d012ae8241780931e717965219#diff-977c29e6cf079bd7307f811df24f99633df603962785c583145eb6250b0e12daR782 ?
