When running in CI, zuul-cloner clones repos to namespaced directories,
e.g. openstack-infra/puppet-cgit/. When running regular git clone, by
default it clones directly into the present working directory, e.g.
puppet-cgit/. This makes the relative directory inconsistent between
developer-run tests and CI jobs. This patch fixes the issue by telling
git clone to clone into the same directory that zuul-cloner would clone
it to.
