This change adds a create-soname-symlinks hook that can be used to ensure that the soname symlinks for injected libraries exist in a container. This is done by calling ldconfig -n -N for the folders containing the injected libraries. This also ensures that libcuda.so is present in the ldcache when the update-ldcache hook is run.
