Ed Page eab2f93453 test: Ensure snapbox works until CARGO_RUSTC_CURRENT_DIR is stabilized ...

Snapbox's polyfill for `CARGO_RUSTC_CURRENT_DIR` looks for the furthest
away `Cargo.toml`.
That works in our repo but won't work as a submodule in rustc.
This uses the `config.toml` hack for setting the variable.

I verified
- Without this, the polyfill is used
- With this, it is used
- Without this on nightly, the official `CARGO_RUSTC_CURRENT_DIR` is
  used
