tests: Mark a sampling test as buggy on llvmpipe.

Browse Source 
Vulkan doesn't mandate whether sampling exactly in the middle between
two levels should resolve to one or the other, while D3D specifies
that it should result into sampling the higher level. llvmpipe
happens to choose the lower one instead, at least in some cases.
