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.
