Add create-soname-symlinks hook

Browse Source 
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 directories containing the injected
libraries.

This also ensures that libcuda.so is present in the ldcache when the update-ldcache
hook is run.
