video: mess with the filte chain to enable zimg IMGFMT_RGB30 output
This was too hardcoded to libswscale. In particular, IMGFMT_RGB30 output is only possible with the zimg wrapper, so the context needs to be taken into account (since this depends on the --sws-allow-zimg option dynamically). This is still slightly risky, because zimg currently will still fall back to swscale in some cases, such as when it refuses to initialize the particular color conversion that is requested. f_autoconvert.c could actually handle this better, but I'm tool fucking lazy right now, and nobody cares anyway, so go away, OK?
