Add an env NetDrvContEnv for container based selftests. This automates
the setup of a netns, netkit pair with one inside the netns, and a BPF
program that forwards skbs from the NETIF host inside the container.
Currently only netkit is used, but other virtual netdevs e.g. veth can
be used too.
Expect netkit container datapath selftests to have a publicly routable
IP prefix to assign to netkit in a container, such that packets will
land on eth0. The BPF skb forward program will then forward such packets
from the host netns to the container netns.

The Python lib based tests report that they are producing
"KTAP version 1", but really we aren't making use of any
KTAP features, like subtests. Our output is plain TAP.
Report TAP 13 instead of KTAP 1, this is what mptcp tests do,
and what NIPA knows how to parse best. For HW testing we need
precise subtest result tracking.

Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.
