[OE-core] [PATCH 3/5] openssh: fixes for systemd

[Chen Qi]

This patch contains a few fixes for the systemd unit files of openssh.
The fixes use the same unit files in Fedora 20 as a reference.

1) Remove sshdgenkeys.service and sshd at .service from SYSTEMD_SERVICE.
2) Fix the dependency and logic of sshdgenkeys.service.
