Some errors, like if rustc is broken, or dylib search path is wrong, will only display non-JSON errors. Show those, too, to make it easier to debug a problem.

…-Simulacrum Fix generating rustc docs with non-default lib directory. If `libdir` is set in `config.toml`, then the tool to generate the rustc docs was unable to run `rustc` because it could not find the shared libraries. The solution is to set the dylib search path to include the libdir. I changed the API of `add_rustc_lib_path` to take `Command` instead of `Cargo` to try to share the code in several places. This is how it worked before rust-lang#64316, and I think this still retains the spirit of that change. Fixes rust-lang#76702
