[patches] Test results improvement

[Daniel Jacobowitz <dan@xxxxxxxxxxxxxxxx>]

You may have noticed that last night's test-results@ mailing had
rather more failures than the previous one from the same branch.
We've been having some problems with ssh to our targets; I switched
the tester to a more sophisticated wrapper script last night, and now
the failing tests are the ones which are actually failing.
