SSH is not enabled unless it is included in products presets

[teclator]

In contrary to the YaST Installer, D-Installer does not enable SSH in any case which is a little bit annoying when doing a network installation which is very common in s390x arch, so it depends on the presets of the selected product to be installed which in case of ALP Bedrock does not include sshd service.

So far would be nice to enable the service if the root SSH key is set at least.
