Fix T47135: VSE importing sound is one frame longer than video. 

Issue is with rounding up of length reported by audaspace for audio part - when it matches nearly exactly
the actual video length, using ceil() would make it one frame longer. Now apply a small (0.0001 frame)
negative offset to prevent this effect.
