vdpasim: fix MAC address configuration
vdpa_sim generates a ramdom MAC address but it is never used by upper layers because the VIRTIO_NET_F_MAC bit is not set in the features list. Because of that, virtio-net always regenerates a random MAC address each time it is loaded whereas the address should only change on vdpa_sim load/unload. Fix that by adding VIRTIO_NET_F_MAC in the features list of vdpa_sim.
