fate/ffmpeg: add test for time limited sub2video instance

Utilizes a subpicture sample with one decodable subpicture for the
test.

Based on a failing test case in reported by Michael in
https://ffmpeg.org/pipermail/ffmpeg-devel/2019-February/240398.html
which at the time had no test case for it.

Additionally, this is the first test case for the presentation
graphics format.
