pg_restore: Fix security label handling with --no-publications/subscriptions.

Previously, pg_restore did not skip security labels on publications or
subscriptions even when --no-publications or --no-subscriptions was specified.
As a result, it could issue SECURITY LABEL commands for objects that were
never created, causing those commands to fail.

This commit fixes the issue by ensuring that security labels on publications
and subscriptions are also skipped when the corresponding options are used.

Backpatch to all supported versions.
