Bug#954344: debian installer don't sets PermitRootLogin to yes in ssh config when no regular user are created

[Илья Пащук <ilusha.paschuk@gmail.com>]

I used the network console feature in install process, so I probably 
will use ssh after installation.

and one other question:

if I add key to root's authorized_keys file with default debian sshd 
configuration, what I will get?
