Only offer hostcertificates if they exist (#15849)
A common bug report is the otherwise harmless sshd logging:
```
Could not load host certificate "/data/ssh/ssh_host_ed25519_cert": No such file or directory
```
This PR simply checks if these files exist before creation of sshd_config and if
they do not exist, doesn't add a reference to them.
Fix #14110 amongst others.
