dev-lang/rust: Disable LTO by default and use thin
We've had a few issues with lto on, and it isn't on by default generally
among Gentoo packages, so this commit flips it to be off by default.
Additionally, in an upstream ticket[0] it was suggested to use thin LTO
rather than fat LTO, so this commit makes that adjustment as well.

[sam: Note that there's a risk of miscompilations with non-thin LTO, per the
upstream bug(s).]
