plugins: handle pixel-aspect-ratio with value 0/1

Browse source 
When downstream negotiates a pixel-aspect-ratio of 0/1, the
calculations for resizing and formatting in vaapipostproc and
vaapisink, respectively, failed, and thus the pipeline.

This patch handles this situation by converting p-a-r of 0/1 to
1/1. This is how other sinks, such as glimagesink, work.
