Paul Sokolovsky 3f9d59c87a tests/net_inet: Move tests which don't require full Internet to net_hosted.
The idea is that these tests can be run with just a test server running
on a test host, with device under test connecting to it, instead of
requiring Internet connection for testing.

Such setup is however WIP, and some tests in net_hosted/ are so far
written to connect to Internet, as there're not test server written
yet. This is expected to evolve over time.
