net: add GSO UDP L4 and GSO fraglists to the list of software-backed …

…types Commit e20cf8d ("udp: implement GRO for plain UDP sockets.") and commit 9fd1ff5 ("udp: Support UDP fraglist GRO/GSO.") made UDP L4 and fraglisted GRO/GSO fully supported by the software fallback mode. We can safely add them to NETIF_F_GSO_SOFTWARE to allow logical/virtual netdevs to forward these types of skbs up to the real drivers.
