LibAudio: Always insert a seek point at sample 0 if not present

Browse source 
Previously, the calculation of the distance to the previous seekpoint
would always behave as if a seek point existed at sample 0, meaning
that it would never place a seek point there. If we instead treat it as
the maximum distance if no sample is present, a seek point will be
placed.
