Bug#1042823: Cannot log into SLBackup web frontend with sshd default configuration

[Guido Berhoerster <guido@berhoerster.name>]

Package: debian-edu-config
Version: 2.12.33

The Debian openssh-server disables login as root using a password by
default.  As noted in the DebianEdu documentation this must be
changed manually for the SLBackup web frontend to work:

> Note: the site will only work if you temporarily allow SSH root login on the backup server, which is the main server (tjener.intern) by default. 

I'm wondering whether we should allow password-based logins from
localhost by default? E.g. through a drop in file
/etc/ssh/sshd_config.d/debia-edu.conf:

Match Address 127.0.0.1,10.0.2.2
    PermitRootLogin yes
