Fix Base-RT-SelfInstall

[grisu48]

Base-RT SelfInstall should use the selfinstall yaml anchors, not the image-based settings.

Absolutely

I wanted to put our Leap Micro 6.1 into a better shape so I reworked this a lot
https://paste.opensuse.org/pastes/4d80b898cb87 (backup)
https://openqa.opensuse.org/admin/job_templates/102?

The UI seem to already contain this change (I'm aware that I need to push it all to git).
I wanted to fix also the Default-qcow and Default-encrypted boot.

Basically all of these remaining faiulres https://openqa.opensuse.org/tests/overview?result=failed&result=incomplete&result=timeout_exceeded&distri=leap-micro&version=6.1&build=4.22&groupid=102

It all seems to be wrongly parametrized as I can boot these fine in virt-manager.

But let's be careful to not overwrite the jobgroup config now :)

About the other changes yes, but this one is clearly wrong. A SelfInstall job should use the selfinstall settings and not the image settings.
