testimage.bbclass: enable ssh agent forwarding

Some targets might use ssh to do their power- or serial-
control. In that case, ssh might need access to the
ssh agent, or otherwise won't work.

So export it into the environment.

Note that the (old) oeqa/controllers/masterimage.py
tries to do that as well by exporting all of BB_ORIGENV
into the test environment. Here in testimage.bbclass we
are a bit more strict and only pass the ssh related
environment variables.
