BuildBot: Select CUDA 10.1 for Blender v2.83 releases

Buildbot has multiple cuda versions installed. Master selects the right
cuda version based on the architecture that is compiled. {D9179}.
When building BlenderLTS it defaults to CUDA 11.1 what isn't able to
compile `sm_30` architecture. This patch selects CUDA 10.1 as default.
