testtools (required by os-testr) still requires unittest2; until
* testtools no longer requires unittest2 and
* we bump up our minimum-supported version of testtools to a version
that doesn't reference unittest2,
we should continue listing unittest2 in lower-constraints.txt (just in
case they ever have a new release).
Admittedly, that seems unlikely at this point -- unittest2's latest
release was back in 2015.
