video: make --deinterlace and HW deinterlace filters always deinterlace
Before this, we made deinterlacing dependent on the video codec metadata (AVFrame.interlaced_frame for libavcodec). So even if --deinterlace=yes was set, we skipped deinterlacing if the flag wasn't set. This is very unreliable and there are many streams with flags incorrectly set. The potential problem is that this might upset people who alwase enabled deinterlace and hoped it worked. But it's likely these people were screwed by this setting anyway. The new behavior is less tricky and easier to understand, and this preferable. Maybe one day we could introduce a --deinterlace=auto, which does the right thing, but of course this would be hard to implement (esecially with hwdec). Fixes #5219.
