worker: Fetch the upstream status code from x-original-status-code

For supporting worker sites we hardcoded the status code to 200 since we don't have access to the status code of the original request. This allows to forward a custom status code via `x-original-status-code` header. Relates to #27. Signed-off-by: Jorge Luis Betancourt Gonzalez <[email protected]>
