python3: assume python3 unless building _packages_ on sys without py3

The jenkins release-new job runs on a CentOS 7 box, which does not
have python3. As a result it runs (autogen.sh and) configure before
producing the dist tar file, converting all the python3 shebangs to
python2 shebangs in the dist tar file.

Then when that tar file is "carried" to, e.g. Fedora koji build
system to build packages, the shebangs are incorrect, despite having
originally been correct in the git repo.

updates: #411
