matroska: do not set invalid default duration if frame rate is zero

If a video track specifies a zero frame rate (invalid but occurs),
this results in a division by zero and subsequent undefined conversion
to integer.  Setting the default duration from the frame rate only
if the latter is greater than zero avoids such problems.
