Accepting request 926674 from home:schubi2

- Use libalternatives instead of update-alternatives. 
From the last try:
"Given the discussion on the openSUSE Factory list concerning the libalternatives, and given the failing on leap, rejecting"
Currently we have already switched about 40 packages to libalternatives. We need it for the next MicroOS release. We do not use libalternatives for previous Leap versions like 15.3. Only the latest factory is for interest. We have already created new RPM Macros, updated old ones and have adapted rpmlint. So it would be nice, if we can have this packages too. ;-)
