Rollup merge of rust-lang#37149 - edunham:more-cargotest, r=alexcrichton

Add some more repos to cargotest

From suggestions at https://users.rust-lang.org/t/what-stable-rust-applications-do-you-use-frequently/7618

This adds some applications which use stable Rust and come with their own lockfiles in their respective trees.

ripgrep, xsv, and bins have 33 unique dependencies between them.

I alphabetized the list by project name because that seems tidier.
