David Michael 416e2c6530 coreos-cargo.eclass: Drop the CoreOS board cross-compilation eclass
With amd64 as the only supported board, the SDK host compiler can
be used with EAPI=7 and the upstream cargo.eclass to build our
Rust projects using 100% upstream Gentoo configuration.

This also drops the std library bootstrapping package along with
the eclass, since that was its only use.
