CUDA_NVCC_EXECUTABLE is not needed, as nvcc is in PATH (#18958)

Summary:
As indicated by f0k: https://github.com/pytorch/pytorch/pull/18495#issuecomment-480178763
nvcc via ccache is already first in the PATH in the instructions I provided, so CUDA_NVCC_EXECUTABLE is not needed.

I re-built to test that it's so.

Thank you!
