translator: set SpawnUpstreamSpan to true

[zirain]

According the doc, EG should set SpawnUpstreamSpan to true.

	//   - If Envoy is used as gateway or independent proxy, or users want to make the sidecar and its
	//     application as different hops in the trace chain, this flag should be set to true.
