avformat/matroskaenc: write a DisplayUnit element when aspect ratio is unknown

We don't currently support values 1 (centimeters), 2 (inches) or 3 (DAR),
only the default value 0 (pixels) which doesn't need to be written.

The fate refs are updated as unknown SAR is now signaled in the output
files with the addition of the new element.
