Skip explicit creation of libnvidia-allocator.so.1 symlink

[elezar]

Since we expect .so.1 symlinks to be created by ldconfig, we don't explicitly request these. This change removes the creation of a libnvidia-allocator.so.1 -> libnvidia-allocator.so.RM_VERSION symlink through the create-symlinks hook.

Question -- does the ordering of hooks in the CDI spec file determine their execution order? E.g. if the update-ldcache hooks comes before the create-symlinks hook in the CDI spec, does the update-ldcache hook always run first?

Yes, I believe that the OCI spec guarantees the order of execution.

Hooks allow users to specify programs to run before or after various lifecycle events. Hooks MUST be called in the listed order.

Note that the Hook lifecycle also affects ordering. A createContainer hook will always run before a startContainer hook regardless of whether it's listed later in the spec.

These changes should be backported to release-1.16.
