Rollup merge of rust-lang#66049 - RalfJung:missing-spans, r=alexcrichton

consistent handling of missing sysroot spans

Due to rust-lang#53081, sysroot spans (pointing to code in libcore/libstd/...) fails to print on some x86 runners. This consolidates the ignore directives for that and references the relevant issue.

I also did that for the generated derive-error-span tests -- but there the script and the tests were not entirely in sync any more since rust-lang#64151. Cc @estebank @varkor
