LibAudio: Don't return a seek point if it is after the desired sample

Browse source 
If the seek table was incomplete, without any seek points available
before the target point, `SeekTable::seek_point_before()` would instead
return the first seek point after the target. Check whether the seek
point is before the target before returning it.
