Fix bug in server Debian package: Fails to start on first install

There has been a very long-standing bug where installation of the
server (the "mandos" Debian package) would fail to start the server
properly right after installation.  It would work on manual (re)start
after installation, or after reboot, and even after package purge and
reinstall, it would then work the first time.  The problem, it turns
out, is when the new "_mandos" user (and corresponding group) is
created, the D-Bus server is not reloaded, and is therefore not aware
of that user, and does not recognize the user and group name in the
/etc/dbus-1/system.d/mandos.conf file.  The Mandos server, when it
tries to start and access the D-Bus, is then not permitted to connect
to its D-Bus bus name, and disables D-Bus use as a fallback measure;
i.e. the server works, but it is not controllable via D-Bus commands
(via mandos-ctl or mandos-monitor).  The next time the D-Bus daemon is
reloaded for any reason, the new user & group would become visible to
the D-Bus daemon and after that, any restart of the Mandos server
would succeed and it would bind to its D-Bus name properly, and
thereby be visible and controllable by mandos-ctl & mandos-monitor.
This was mostly invisible when using sysvinit, but systemd makes the
problem visible since the systemd service file for the Mandos server
is configured to not consider the Mandos server "started" until the
D-Bus name has been bound; this makes the starting of the service wait
for 90 seconds and then fail with a timeout error.

Fixing this should also make the Debian CI autopkgtest tests work.

* debian/mandos.postinst (configure): After creating (or renaming)
                                      user & group, reload D-Bus
                                      daemon (if present).
