lang/rust: update to 1.29.1

[jbeich]

Summary

According to upstream diff and notes it only carries a small security fix. While fix is in standard library because Rust (like Go) defaults to static linking every consumer has to be rebuilt.

Test Plan

• poudriere bulk -t lang/rust is green on 10.4 i386/amd64, 11.1 i386/amd64, 11.2 i386/amd64, 12.0 i386/amd64
• poudriere bulk -tj 112amd64 -f rust-consumers.list is green except security/kr which fails for what looks like an unrelated issue.

I was going to suggest the same once 1.29.1 has landed. I believe @dumbbell is already working on updating lang/rust (see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230470#c6).

Please bump the minimum version in cargo.mk too. It's long overdue anyway.

[jbeich]

• Bump required version for USES=cargo to make sure consumers get the fix
• Mark testing as done

Hi!

I tested (poudriere testport) a similar patch to lang/rust on 10.4 and 11.1, both amd64 and i386, and it works.

I will continue to look into LibreSSL support, but you can commit this already :-) Thank you!

Rust < 1.29 doesn't appear to be affected, so the change is unnecessary. Let's go with D17346 instead.
