run-tests: error out on `--local --with-[c]hg`

I don't see much reason to allow these combinations. You could use
--local and override only one of --with-hg or --with-chg, but I don't
see much practical use for that. It would be easy to work around
anyway by passing both --with-hg and --with-chg. By erroring out, it
makes the code a bit easier to reason about to allow the next few
patches.
