[slurm-users] error building debug packages on ubuntu 24.04

It was unable to find lib/security/pam_slurm_adopt.so It was built as lib64/security, not lib/security. ./debian/slurm-smd-libpam-slurm-adopt.install needs to be lib64/security/pam_slurm_adopt.so More likely, it needs to be built dynamically, so it will work everywhere.
