[debian] Move python-unittest2 >= 0.7.0 as runtime dependency It seems to me that this is not used during Debian package build (tests are not run), but should be needed at runtime with the cubicweb-dev package. Also, at the moment, we have no pbuilder setting with this package available and it blocks the release.

missing-dep-for-interpreter make => make | build-essential | dpkg-dev (usr/*/cubicweb/skeleton/debian/rules.tmpl)
