Bug#837733: openssh-server: debconf "openssh-server/permit-root-login" provides no way of specifiying "PermitRootLogin yes"

[Bastian Germann]

With commit de911c73504da8 (version 1:7.4p1-1), setting
openssh-server/permit-root-login to false results in "PermitRootLogin yes".

So this issue can be closed.
