Update TOX_CONSTRAINTS_FILE for stable/wallabystable/wallaby

Update the URL to the upper-constraints file to point to the redirect
rule on releases.openstack.org so that anyone working on this branch
will switch to the correct upper-constraints list automatically when
the requirements repository branches.

Until the requirements repository has as stable/wallaby branch, tests will
continue to use the upper-constraints list on master.
