        Remove references to systemd-sysv-convert
    
        Packaging guidelines have been amended to not require systemd for scriptlets,
        see https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_scriptlets.
    
        The comment duplicates what the macro contains.
    
        systemd-sysv-convert binary was removed in 2013, trying to call it is
        unlikely to succeed.
    
        chkconfig binary is provided by the chkconfig package, which is not in
        Requires. (And makes little sense to call nowadays anyway.)
