[f-spot] Call Pixbuf.Savev directly instead of implementing the binding again

[Ruben Vermeersch <rubenv src gnome org>]

commit 706b6e1cbd4f82571c451cb1fdd411d99ecea640

    Call Pixbuf.Savev directly instead of implementing the binding again
    
    The methods Pixbuf.Savev allows to specify arbitrary parameters to
    gdk_pixbuf_save. So, there is no need to adding the binding
    to the C function again.
