Yeah, Ubuntu 14.04 is stuck on the ancient OpenJPEG 1.3. I think it's fine
to proceed with this patch since:

1) OpenJPEG 1.3 sets AV_CODEC_CAP_EXPERIMENTAL[1], so support for it was
already kinda experimental.
2) This doesn't impact old versions of ffmpeg. If people are building
ffmpeg 3.5+ on Ubuntu 14.04 on their own, then they can also build OpenJPEG
2.1+ on their own.
