[debian] Update debian packaging (closes #16133259)
- use dh_python, pybuild and debhelper>=9,
- refactor and simplify the debian/rules,
- rename binary packages (but cubicweb-ctl) to python-xxx
- remove daemon handling stuff (initscripts...) from cubicweb-ctl (one should
now use a standard WSGI delivery method),
#!/bin/sh -e
if [ "$1" = "purge" ] ; then
rm -rf /etc/cubicweb.d/
rm -rf /var/log/cubicweb/
rm -rf /var/lib/cubicweb/
