Add two tests using NetDrvContEnv. One basic test that sets up a netkit
pair, with one end in a netns. Use LOCAL_PREFIX_V6 and nk_forward BPF
program to ping from a remote host to the netkit in netns.
Second is a selftest for netkit queue leasing, using io_uring zero copy
test binary inside of a netns with netkit. This checks that memory
providers can be bound against virtual queues in a netkit within a
netns that are leasing from a physical netdev in the default netns.

I think we might also need something like:
