Title: Make helpers work with latest cmdtest

Recent vito/cmdtest update \[1] (from about a month ago) changed cmdtest.OutputWrapper to
take an io.Writer rather than an io.Reader. This means that the latest cf-acceptance-tests
don't compile \[2] with the latest cmdtest version.

This change updates teeStderr/out to use a MultiWriter rather than a TeeReader
which makes go happy, and still prints the output properly in verbose mode.
