Add the cache/hash/lib paths to ld_library_path

[ahendriksen]

These paths were omitted before, leading to problems with more advanced use cases like Nvidia Nsight Compute.

Before

Use ncu to profile a CUDA program:

LD_LIBRARY_PATH=$(nixglhost -p) ncu  ./cuda-program

Get a failure:

==PROF== Connected to process 35030 (/home/scratch.ahendriksen_gpu/projects/2023-03-markov-clustering-raft/build/test_csroo)
==ERROR== Failed to prepare kernel for profiling

==ERROR== The application returned an error code (9).                                                             
==ERROR== An error occurred while trying to profile.                                                                
==WARNING== No kernels were profiled.                                                                             
==WARNING== Profiling kernels launched by child processes requires the --target-processes all option.        

Rerun with LD_DEBUG=libs:

LD_DEBUG=libs LD_LIBRARY_PATH=$(nixglhost -p) ncu  ./cuda-program

See in the output that it cannot find libnvidia-ptxjitcompiler.so.

Check that the ptxjitciompiler so file is indeed copied to the cache:

And that the nixgl-host/hash/lib/ paths are not included in the nixglhost paths:
