m_decodingUnitDpbDuParamsInPicTimingSeiFlag was not copied

As in specification: "The value of pt_sublayer_delays_present_flag[ bp_max_sublayers_minus1 ] is inferred to be equal to 1"

Currently m_latestDRAPPOC for pictures which follow DRAP is always MAX_INT.

This prevents checkConformanceForDRAP() from checking active ref pic constraints
