Don't log TransportGitSsh error stream to JVM stderr
This is an API function, not a user interface routine. We should not
be printing messages from the remote side to our console. Instead we
should buffer them, and allow a TransportException to be thrown which
contains the message data. Higher level user interface routines
can then catch that exception, and display the message, if any, in
a form that is appropriate to the context.
