Rollup merge of rust-lang#128060 - alexcrichton:include-wasm-component-ld-for-real-this-time-maybe-let-see-after-this-merges, r=onur-ozkan

Fix inclusion of `wasm-component-ld` in dist artifacts

This is another accidental omission from rust-lang#126967 (in addition to rust-lang#127867) which fixes an issue where `wasm-component-ld` isn't distributed via rustup just yet because while it's present in the sysroot it's not present in the tarballs.
