Skip the parts that cannot be run on the host due to lack
of IPv6 support or a second interface to bind on, and warn
appropriately.
Without no strong requirements (besides being Linux only, in which case
the test is skipped) left, just add this test to the default in
test_runner.

c8330d4 qa: Use node.datadir instead of tmpdir in test framework (MarcoFalke)
Pull request description:
Commit c53c9831ee introduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir.
This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.

Prevents OSX firewall allow-this-application-to-accept-inbound-connections
permission popups and is generally safer.
To prevent binding to 127.0.0.1, set self.bind_to_localhost_only = False.
