[glib] Update config.h.win32.in for Newer Windows

    Update config.h.win32.in for Newer Windows
    
    Make use of if_indextoname() and if_nametoindex() when building against
    Window Vista/Server 2008 or later, as these are provided by the system.
    
    This is not turned on by default as we still want to support XP and
    Server 2003-turn this on by changing _WIN32_WINNT to 0x600 or later prior
    to compiling GLib.
