Destroyed nested container on `attachContainerOutput` failure.

After launching a container, the `LAUNCH_NESTED_CONTAINER_SESSION`
handler calls into `attachContainerOutput()`. Previously, if
`attachContainerOutput()` returned an HTTP response code other than
200, we didn't destroy the nested container. From the point of view of
API users, if `LAUNCH_NESTED_CONTAINER_SESSION` returns an error, then
no nested container should be left in the `RUNNING` state. This patch
fixes this issue by destroying the nested container when HTTP errors
are returned by this call to `attachContainerOutput()`.
