diracdec: fix original Dirac Low Delay profile

The version structure in the main decoder context was not (and
apparently has never been) populated since it was added.
Still, having VC-2 break the existing Dirac Low Delay mode was odd and
easily avoidable had the specifications authors noticed/cared.
