Tox tests are run on developer machines and on long lived slaves. We
should not leave lots of directories like
/tmp/python-openstackclient-tox_install-sdnltRu lying around.
Instead delete the temporary directory after our run.
Remove also an obsolete comment.

The usage of zuul-cloner in tox_install breaks post and periodic jobs.
Update the script, it does not need to handle unconstrainted installs
anymore (see tox.ini). There's no need to set ZUUL_BRANCH explicitely
- it's set via the environment and branch is passed in as well.
Note that this script is needed for the edit-constraints call, add a
comment.
