iotests: Make redirecting qemu's stderr optional
Redirecting qemu's stderr to stdout makes working with the stderr output
difficult due to the other file descriptor magic performed in
_launch_qemu ("ambiguous redirect").
Add an option which specifies whether stderr should be redirected to
stdout or not (allowing for other modes to be added in the future).
