Blender spec file has command that removes cycles headers from the package.
It results in broken GPU rendering with cycles, example with CUDA:
```
Compiling CUDA kernel ...
"/usr/local/cuda/bin/nvcc" -arch=sm_61 --cubin
"/usr/share/blender/2.79/scripts/addons/cycles/source/kernel/kernels/cuda/kernel.cu"
-o
"/home/mateusz/.cache/cycles/kernels/cycles_kernel_sm61_52CFAD0EF032EEC8D0F7A458B14C818A.cubin"
-m64 --ptxas-options="-v" --use_fast_math -DNVCC -D__KERNEL_CUDA_VERSION__=92
-I"/usr/share/blender/2.79/scripts/addons/cycles/source" 
/usr/share/blender/2.79/scripts/addons/cycles/source/kernel/kernels/cuda/kernel.cu:21:10:
fatal error: kernel/kernel_compat_cuda.h: No such file or directory
 #include "kernel/kernel_compat_cuda.h"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
CUDA kernel compilation failed, see console for details.
```

Removing `find %{buildroot}%{_datadir}/%{name}/%{_version}/scripts/ -name "*.h"
-print -delete` from line 321 as shown here:
https://build.opensuse.org/package/rdiff/home:mati865:branches:graphics/blender?linkrev=base&rev=2
resolves issue and Blender works fine.

However it causes rpmlint errors:
```

is

packages.

```

On Fedora those headers are packed in the main package causing rpmlint warnings
which are ignored:
