qemu-iotests: Fix stderr handling in common.qemu

The original intention was to pipe stderr of qemu into $fifo_out.
However, the redirections were specified in the wrong order for this.
This patch fixes it.

Now qemu's output on stderr can be retrieved with _send_qemu_cmd, which
applies several useful filters on the output that were missing before.
