bug#70323: [PATCH v3 1/2] gnu: vtk: Update to 9.3.0

[Andreas Enge]

Hello,

I just realised that the patches already built on QA when they were put
together as one; so there is no real point to wait for QA again.
I have checked that freecad still builds on x86_64 and pushed the two
patches.

Thanks!

Andreas
