With netns handling localhost now, existing tests no longer
need special handling. The tests set up their connections to
localhost, and the connections work without fuss.
Remove the special handling for tests.
Also remove the hostinfo.TestCase support, since this was
the only use of it. It can be added back later if really
needed, but it would be better to try to make tests work
without special cases.

Several other AWS services like App Run and Lightsail Containers
appear to be layers atop Fargate, to the point that we cannot easily
tell them apart from within the container. Contacting the metadata
service would distinguish them, but doing that from inside tailscaled
seems uncalled for. Just report them as Fargate.

Treat automated tests as their own, unique environment
rather than the type of container they are running in.
