Rollup merge of rust-lang#122136 - Kobzol:opt-dist-lookup-logic, r=Mark-Simulacrum

Include all library files in artifact summary on CI

It's not worth it to maintain any custom logic here. Just print all files in the `lib` directory, this should be forward compatible.

This fixes rust-lang#121866, based on rust-lang#121967.
