opt-dist: dont overrwite config.toml when verifying 

This is another step toward making opt-dist work in sandboxed environments

opt-dist verifies the final built rustc against a subset of rustc test
suite. However it overwrote the pre-existing `config.toml` [^1],
and that results in ./vendor/ directory removed [^2].

Instead of overwriting, this patch use `--set <config-value>` to
override paths to rustc / cargo / llvm-config.

[^2]: 8679004993/src/bootstrap/bootstrap.py (L1057)
