openssh has been changed to install the distro default configuration no longer
in /etc, but in /usr/etc

See SR https://build.opensuse.org/request/show/888799

This currently results in installation-images failing to build:

[  446s] Creating user sshd (SSH daemon) with uid 483 and gid 483.
[  446s] running postin script
[  446s] Updating /etc/sysconfig/ssh ...
[  446s] cp: cannot stat 'tmp/rescue//etc/ssh/sshd_config': No such file or
directory
[  446s] unable to access /etc/ssh/sshd_config at lib/AddFiles.pm line 812.
[  446s] make: *** [Makefile:172: rescue] Error 1
[  446s] error: Bad exit status from /var/tmp/rpm-tmp.hlxgWc (%build)

In line with https://en.opensuse.org/openSUSE:Packaging_UsrEtc, i-i should:

* copy the files from /usr/etc/ssh (if exist) and /etc/ssh (if exist); it is up
to openssh to do 'the right thing out of the presence of those files' then.
