graphics/libskiasharp: bump the exact revision used by SkiaSharp 3.116.1
On linux libskiasharp.so is provided by the SkiaSharp nuget built as a
submodule, libskiasharp does not really have any release and tags. From
Now on, use the hash used by the SkiaSharp version used by jellyfin.
While here bump the bundle libjpeg_turbo version to the version this
release of libskiasharp has been tested with.
