the init script could not start the daemon

"su - www-data" answers "This account is currently not available": the system
user that runs the daemon has /usr/sbin/nologin as its shell, and that is the
case for www-data on debian. The init script used it in both start branches,
start and devstart, so the service did not start at all.

"-s /bin/bash" is passed to the two su. It is the bare minimum: giving the
system user a real shell would be the wrong fix.

Checked in the debian 13 container: installed with "INSTALL.sh system",
enabled with systemctl (systemd accepts LSB scripts through
systemd-sysv-install), and after a restart of the container the daemon, nginx
and postgresql come back up by themselves, with the site answering on 80 and
443.
