Move yum/dnf protection removal config file under /usr
    
    https://github.com/uapi-group/specifications/issues/76
    
    Actually, add a new file under /usr, but keep the old file in /etc
    because it's still needed for dnf. The new file in the new location
    is useful because it means that we get the correct behaviour even when
    /etc is emptied (on systems with new dnf version).
    
    dnf5 reads the new location:
