CUDA: Enable support on QNX
This fixes the following two issues with the CUDA support on QNX:
* cuda target name is not derived correctly (should be `aarch64-qnx`).
* linking `cudart` must not be linked against `rt`, `dl`, `pthread`.
This enables to use cmake's native cuda support on QNX.
Fixes: #21381
