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.

+This directory contains network tests which require just "peer to peer"
+network connection between test host and device under test, instead of
+full Internet connection.
+
+Note that setup for these tests and tests themselves are WIP, and may
+not yet fully correspond to the functional specification above.
+
+So far, these tests are not run as part of the main testsuite and need
+to be run seperately (from the main test/ directory):
