Storing and restoring alterntives during update manually
    
    Fixing:
    Bug 2001567 - update of JDK/JRE is removing its manually selected alterantives and select (as auto) system JDK/JRE
    
    The move of alternatives creation to posttrans to fix:
    Bug 1200302 - dnf reinstall breaks alternatives
    Had caused the alternatives to be removed, and then created again,
    instead of being added, and then removing the old, and thus persisting
    the selection in family
    
    Thus this fix, is storing the family of manually selected master, and if
    stored, then it is restoring the family of the master
