Fix errors preventing novajoin to start on Python 3

This patch also moves the novajoin-install and novajoin-ipa-setup
scripts to the default python scripts directory. This is because
there is no other way to fixup the #! line for python3, apart from
modifying setup.py, which is managed by the global requirements repo.
