vdpa_sim_net: Offer VIRTIO_NET_F_STATUS
VIRTIO_NET_S_LINK_UP is already returned in config reads since vdpasim
creation, but the feature bit was not offered to the driver.
Tested modifying VIRTIO_NET_S_LINK_UP and different values of "status"
in qemu virtio-net options, using vhost_vdpa.
Not considering as a fix, because there should be no driver trusting in
this config read before the feature flag.
