Subject: [PATCH] Set C++17 when generating SYCL programs

Intel's SYCL implementation requires C++17 and this is baked by the SYCL
2020 specification, see:
- 3.9.1. Minimum version of C++ [1]
- 3.3. Normative references [2]

[1]: https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#sec:progmodel.minimumcppversion
[2]: https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#sec:normativerefs

Without this tweak, generated makefiles are not suitable for building
SYCL programs with intel/llvm.
