Bug#1093169: blender: Missing brushes for sculpt, texture paint and weight paint modes

[coffe toochunky]

I figured out a workaround for now. blender has a seperate project for
their assets. you can download the brushes from there:
sudo curl --create-dirs --output
/usr/share/blender/datafiles/assets/brushes/essentials_brushes.blend
https://projects.blender.org/blender/blender-assets/media/branch/blender-v4.3-release/working/brushes/essentials_brushes.blend
sudo chmod o+rx /usr/share/blender/datafiles/assets/
/usr/share/blender/datafiles/assets/brushes
