vd_ffmpeg: fix aspect ratio problems with recent FFmpeg

Browse Source 
The code left ctx->last_sample_aspect_ratio at 0/0 when allocating a
context. In older FFmpeg versions av_cmp_q() against 0/0 always said
the numbers are equal; but this changed recently, triggering incorrect
overwrite of container aspect ratio. The logic looks like it'd need
further fixes, but for now just initialize last_sample_aspect_ratio to
0/1; this should restore the previous behavior from before FFmpeg
changes, which worked well enough for the most common cases.
