Rollup merge of #142318 - Urgau:cleanup-rust-src-remap, r=jieyouxu
Cleanup `rust-src` remapping and real dir

When remapping, `bootstrap` sets `CFG_VIRTUAL_RUST_SOURCE_BASE_DIR` to indicate what the base build dir (`/` of this repo) was remapped to, ie. `/rustc/...`.

It is therefore impossible when stripping `/rustc/...` from a remapped path to be inside the our `library/` directory, nevertheless we have code that assumed it was possible and helpfully tried to correct it. I don't why this was done, but it's not necessary.

~~The normalization in compiletest of `$SRC_DIR_REAL` was also slightly wrong, it ate the `library` part for no reason.~~ EDIT: there is a reason, it affects too much tests otherwise
