Revert C++17 usage of std::exclusive_scan

* Unfortunately on some systems such as the Nvidia Jetson, while the
  compiler supports C++17, the STL implementations are incomplete.
  One such missing implementation is std::exclusive_scan, so this
  patch reverts to the old way of manually computing prefix sums.
