Update Perlmutter env

libsci was being linked twice, from OpenMP and the libsci module. This caused a warning at runtime which which was making the regression test fail to parse the JSON output... Disabling that module results in another error: a few CUDA test fail to link with the following error:
test/celeritas/CMakeFiles/celeritas_phys_Particle.dir/phys/Particle.test.cu.o: undefined reference to symbol 'dlclose@@GLIBC_2.2.5'. I looked at the symbol Particle.test.cu.o and there is indeed dlclose, it is not clear to me who is bringing that symbol there.

The failure only happens with VecGeom build, the ORANGE build has -ldl in the linker invocation, I don't know why it's different for VecGeom. Just work around it by setting CMAKE_EXE_LINKER_FLAGS...

Good to get that debugged; and cray libs are the worst. Thanks @esseivaju !

@pcanal the missing dl might be a RDC link magic issue 😬

I checked a verbose CI run, and you can see that orange links to libdl here too, whereas VecGeom does not. It doesn't fail to link though, so maybe something in my environment is injecting that dependency in my VecGeom build 🤔
