lutea: update shaderc for mpv and mpv's libplacebo dependency
This fixes an issue where shaderc can compile shader code but can't
optimize it.
When attempting to broadly apply the update for shaderc, qtwebengine6
fails to build and instead of going through that long build process
again, I've decided to just target the package I was having issues
with.
