[CONTINT-3688] Enable origin detection from client when origin detection is enabled

[AliDatadog]

What this PR does / why we need it:

This PR sets the variable DD_DOGSTATSD_ORIGIN_DETECTION_ENABLED to true when dsd origin detection is enabled. Without it, we can't retrieve container tags on UDP even if the container-id is sent with metrics. https://github.com/DataDog/datadog-agent/blob/54e9ed2fde3620f8fe8181491f3ecc198538900a/comp/dogstatsd/server/parse.go#L70
