Sec: Persistent ssh host keys
I changed the valid ssh-host-keys from both rsa and ed25519 to
only ed25519 and moved them to `/srv/ssh` to make them persistent.
In addition to that, I also increased the rounds for the ed25519 key to
1000.
This fixes the ssh-host-key issue introduced by pull request #5.

Fixes: #5
