Unrolled build for rust-lang#138875

Rollup merge of rust-lang#138875 - thaliaarchi:trusty-build, r=randomPoison,saethlin

Trusty: Fix build for anonymous pipes and std::sys::process

PRs rust-lang#136842 (Add libstd support for Trusty targets), rust-lang#137793 (Stablize anonymous pipe), and rust-lang#136929 (std: move process implementations to `sys`) merged around the same time, so update Trusty to take them into account.
