Summary

For Linux binaries, sopt->sopt_td may be null. And there's also no
need to check it, since struct l_ucred has the same layout on 32-bit
systems as on 64-bit ones.

PR: 295333
Reported by: Miguel Gomes <miguel.dias.gomes@protonmail.com>
Fixes: 1d24638d3e8 ("Fix LOCAL_PEERCRED in 32-bit compat mode")
MFC after: 3 days

Test Plan

Tested with Rust's Nix crate's test suite, built for Linux,

		both 64-bit and 32-bit.
