cuda.profile: Should have CPATH and LIBRARY_PATH

[donald]

prun cuda make would work out of the box, if the profile would set CPATH and LIBRARY_PATH in addition to LD_LIBRARY_PATH.

It works for me with this;

export CPATH=/pkg/cuda-11.8.0-0/include${CPATH:+:$CPATH}
export LIBRARY_PATH=/pkg/cuda-11.8.0-0/lib${LIBRARY_PATH:+:$LIBRARY_PATH}
. /pkg/cuda-11.8.0-0/profile
