[Cin] Deleting old libs from thirdparty/src

If new libs work good enough ... /cinelerra-5.1/thirdparty/src/tiff-4.1.0.tar.xz /cinelerra-5.1/thirdparty/src/libvpx-1.11.0.tar.xz /cinelerra-5.1/thirdparty/src/libogg-1.3.4.tar.xz /cinelerra-5.1/thirdparty/src/libjpeg-turbo-2.1.0.tar.gz /cinelerra-5.1/thirdparty/src/libaom-v3.2.0.tar.xz And associated patches ... Also, I think we can remove old ffmpeg.git patches, and replace them with renamed copies of ffmpeg-5.1 patches .... It will work hopefully until some break in ffmpeg :)
