btf, scripts: Exclude Rust CUs with pahole
commit c1177979af9c616661a126a80dd486ad0543b836 upstream.
Version 1.24 of pahole has the capability to exclude compilation units (CUs)
of specific languages [1] [2]. Rust, as of writing, is not currently supported
by pahole and if it's used with a build that has BTF debugging enabled it
results in malformed kernel and module binaries [3]. So it's better for pahole
to exclude Rust CUs until support for it arrives.
