selftests/net: add netkit container env and test
Add a new Python selftest env NetDrvContEnv that sets up a pair of
netkit netdevs, with one inside of a netns, and a bpf prog that forwards
skbs from NETIF to the netkit inside the netns.
NETIF = "eth0"
LOCAL_V6 = "2001:db8:1::1"
REMOTE_V6 = "2001:db8:1::2"
LOCAL_PREFIX_V6 = "2001:db8:2::0/64"

I will use this series for queue leasing selftests. Include a basic ping
test in this series as demonstration.
