avformat/dashdec: Also fetch final partial segment

Browse Source 
Currently, the DASH demuxer omits the final segment for a non-live
stream (using SegmentTemplate) if it is shorter than the other segments.

Correct calc_max_seg_no to round up when calulating the number of
segments instead of rounding down to resolve this issue.
