Utility function to convert a GLib.Variant of type 'aau' representing an array
of NetworkManager IPv4 routes (which are tuples of route, prefix, next hop,
and metric) into a GLib.PtrArray of NM.IPRoute objects. Note that invalid routes
are discarded but the valid routes are still returned.
Since 1.46, an empty list is returned if the variant type is not valid
(before it was checked as assertion)
