GWin32VolumeMonitor: Sort the volumes correctly
Use a static GQueue to form the GList of mounts by appending (which is fast, because GQueue tracks the tail pointer of its internal GList), then return that GList. This way we don't need to form the list by prepending, which would have made it necessary to reverse it before returning. If the list is not ordered correctly, local drives in GTK places sidebar are shown in reverse order.
