Regenerate ld.so.cache

This file is mandatory for programs to know where to look where to find dynamic linked libraries
The problem arise within containers that add .so files to the container during the OCR definition
If we consider nvidia-container-runtim, these .so for example concern cuda libs, nvidia drivers, so that the versions on both the host and
the guest/container are consistent, to avoid version conflict as much as possible, and provide additional tools, like nvidia-smi,
by default)
If ldconfig is not run as a precommand then the latest added libs are not cached
This does not happen with the nvidia-container-runtime because it runs ldconfig
Looks like for some reason the GKE container runtime does not
The provided command should be enough to fix most issues
