cuda: fix `cuda.find_library()` hardcoded to yield true

* Previously, cuda would just plainly prepend `-l` to the libname.
* By relying on the host compiler to find libraries, we now get
  more subtle failures, such as CUDA modules not being found
  anymore.
* We need to simplify these CUDA modules when nvcc is used for
  linking, since this may have side-effects from the cuda toolchain.

Closes: #13240
