run-tests: allow bisecting a different repo

Add `--bisect-repo` flag which accepts a different repo to bisect.

3rd party extensions may reuse `run-tests.py` from core to run tests. Test
failure could be caused by either a core hg change or the 3rd party
extension code itself. Having a way to specify which repo to bisect is
useful.
