Add a selftest for netdev generic netlink. For now there is only a
single test that exercises the `queue-get` API.
The test works with netdevsim by default or with a real device by
setting NETIF.
Add a timeout param to cmd() since ethtool -L can take a long time on
real devices.

Using "with" on an entire driver test env is supported already,
but it's also useful to use "with" on an individual nsim.

net/lib/py/nsim.py already contains the most useful parts
of the netdevsim wrapper classes. Reuse them.

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.
