[libwnck] build: Require gtk+-3.0 >= 3.4.0

    build: Require gtk+-3.0 >= 3.4.0
    
    The fixes related to mouse wheel scrolling require GTK+ 3.4.0. We could
    use some ifdef to still build with earlier versions of GTK+, but people
    upgrading GTK+ without rebuilding libwnck would see the bugs again. So
    it's simpler to just require a recent version of GTK+.
