Unfortunately, this will cause scp to skip using ssh completely as the
-S option specifies a replacement for ssh. We could either 1) make a
different wrapper that runs the scp under test via ssh, 2) add an option
to scp that lets it specify an explicit path to a scp binary to run on
the remote end or 3) remove scp from the test entirely.

I don't much like (2) as I don't want to add more options.
