Fix compilationw with amgcl/vexcl and without CUDA/OpenCL.

There is no reason to omit WellContributions if neither CUDA nor
OpenCL is found as the implementations/functions only use C++-
To the contrary, the defines used for deactivating were not
consistent with usage elsewhere and resulted in compiler erorrs
for exotic configuration
