[gnome-boxes] express,winxp,win2k3: Admin password required

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

    express,winxp,win2k3: Admin password required
    
    We need to set admin password to "*" to unset it. The same is not true
    for 'net' commandline we use to setup user account so we need to do
    admin password substitution differently for Windows XP and 2003.
