Due to bug introduced at initial datadog-sketches API implementation, `host` label was incorrectly obtained from `Tags` structure. While actually it's present directly at root of protobuf message. This commit properly attaches `host` label in such case. Fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10557
