Remove SSH host keys after installing the custom version of sshd (#10633) (#11140) 
* Remove SSH host keys after installing the custom version of sshd

Signed-off-by: Saikrishna Arcot <sarcot@microsoft.com>

* Use an override for for sshd instead of overwriting the service file

Don't overwrite upstream's .service file, and instead use an override
file for making sure the host key(s) are generated.
