[PATCH 3/3] drivers: always enable the null net driver [RFC]

[Bruce Richardson]

Having the net_null driver always available can be convenient and allows
use by unit tests, so add this trivial driver to the always-enable list.

I'm not sure if we want this to be always enabled or not, so sending
this as an RFC. I can see definite advantages to doing so, but I also
dislike having too many components on the always-enable list.

Since I'm ambivilent myself, including this patch so the community can
decide.
