Skipping because:
larsu: I get `open failed: administratively prohibited: open failed`
larsu: ssh somehow disallows making a side channel for the forward
larsu: there's an option that controls it, but it's set to "yes"
larsu: I've straced the sshd, with no luck coming closer
We'll deal with this later, possibly together with the rest of
the skipped test cases.

compatible, making them the same as on master branch
