[gparted] Use gksudo, if available, in gparted.desktop

    Use gksudo, if available, in gparted.desktop
    
    If gksu was installed on a KDE system (tested with kubuntu 12.04 LTS),
    then gksu would prompt for the password three times and always fail to
    load gparted.  In a prior version of kubuntu 8.04 LTS, gksu would
    properly invoke gparted from the "K --> System --> GParted" menu
    entry.
    
    Since gksudo also works on KDE (and kubuntu 12.04 LTS), add gksudo to
    the root privilege invocation search list ahead of gksu.
    
    Note that gksu has been kept for backwards compatibility with systems
    that provide only gksu and not gksudo.
    
    Related to Bug #687813 - Use kdesudo on KDE, as gksu is not
                             installed by default
