Omit stdarch test crates from the rust-src component 
These crates aren't necessary for building the standard library. This
saves 30MB of disk space.

This should have been

"library/stdarch/Cargo.toml",

I think. In Rust 1.61.0, rust-src includes src/rust/library/stdarch/Cargo.toml, which includes

[workspace]
members = [
  "crates/stdarch-verify"

This didn't show up when testing with -Zbuild-std since the standard list of crates to include when building std does not include stdarch, but it will show up if a user explicitly requests stdarch. Or, perhaps more importantly, because of #95736, many editors (like IntelliJ) won't treat the root of rust-src as a workspace, and will instead recurse into all the sub-crates directly, which then includes stdarch.

Right, my bad.
