Request to hide builddir at sanity check step; Faiss-1.7.4-foss-2023a-CUDA-12.1.1.eb: python -c "import faiss" does not work.

[ThomasHoffmann77]

python -c "import faiss" does not work for the installed module although sanity check ran through.
The sanity check runs through, because $EBROOTFAISS/lib/python3.11/site-packages/faiss/_swigfaiss.so has rpath set to %(builddir)s/easybuild_obj/faiss/python, which contains libfaiss_python_callbacks.so
A solution could be to have libfaiss_python_callbacks.so in $EBROOTFAISS/lib instead.

I wonder if it would be possible to generally make the builddir temporarily unavailable during the sanity check step
