CurvesPrimitiveEvaluator : Fix build on macOS

6fa3f54 introduced `CurvesPrimitiveEvaluator::Result::linear()`, which Clang considers to be shadowing the `linear` template parameter of `CurvesPrimitiveEvaluator::Result::init()`. This fix takes the simple approach and renames the template parameters.
