Avoid using zuul-cloner for Upstream-Id
Avoid using zuul-cloner for Upstream-Id

With review.rdo's Zuul moving to Zuul v3, the zuul-cloner command
no longer behaves as it should.

This is the first (and most urgent) change in run_tests.sh to adapt,
to avoid using zuul-cloner to get the source repository when using
Upstream-Id: in the commit message.
