Disable opencl, cuda and nvml when configuring hwloc

Without explicitly disabling them and if a system where hwloc
is being build has opencl/cuda/nvml installed those libraries
will become hwloc dependencies which would force umf to link with
them.

The problem manifested on a system where opencl was installed and
umf compilation failed due to missing clGetDevices symbol.
