Add patch fixing libs/filamat/src/GLSLPostProcessor.cpp for newer spirv-cross
@roehling This fix the issue introduced by the new version of spirv-cross https://bugs.debian.org/1029503.
Fortunately (or not), only two packages depend on spirv-cross: filament and mpv, but only filament is affected by this issue. Fixing this issue in filament will allow to provide the new spirv-cross in Bookworm and thus having all khronos related packages aligned on the same sdk-1.3.236.0
tag.
