Don't check the specific build-std output#16551

This particular test was failing occasionally because the order of the output is not deterministic. Sometimes `test` would run first, and sometimes `rustc-std-workspace-std` would run first. This is because they start in parallel, and it is a race which one prints first. The exact output here isn't particularly interesting. I would prefer to not check the particular structure of the standard library, so this just elides all the output.

There was a problem hiding this comment.
Can we keep it like this, and maybe add a comment like line 147, to ensure it doesn't update index?

This makes sure that cargo doesn't try to update the index or do anything else before compiling. Requested in #16551 (comment)
