[Cin] AOM 3.8, again

[Andrea paz]

> hopefully fixed for good ...
With your libaom.sh (with the correction of libstvav1 to libsvtav1)
the compilation was successful. [All this was before your latest
patch.]
I also loaded your "av1-svt.webm" preset and rendered the exr sequence:

** rendered 273 frames in 5.586 secs, 48.872 fps

With the normal "av1.webm" preset (and system aom) I rarely get to 48
fps, most of the time it stops at 30 fps.

But the most indicative test is rendering a "dnxhr + h264+ vp9" video;
with av1.webm I get to 12.5 fps. With av1-svt.webm I get to 53 fps!
Trying to use the crf=18 (visually lossless) option I get 59 fps.

av1-vaapi.webm needs next-generation GPUs to run, apparently,
av1-svt.webm needs even just a simple CPU with AVX instructions to
run. I guess those with an Intel Arc/Xe2 video card will have even
better performance.

I will try to test your new patch later.
Thanks for all the work you did and sorry for all my mistakes.
