dev-util/nvidia-cuda-toolkit-10.1.105: Fix installation location of executables

Fixes failures when invoking nvcc. link.stub and prelink.stub need to be
in crt subdirectory otherwise nvcc fails to find them.
Also extras/demo_suite were not executable.

Thanks to Jan Vesely and Nathaniel R. Lewis, this fix was derived from
patches from them.
