The newer ifupdown-ng bond executor uses bond-members instead of bond-slaves and rewrites the term as support for legacy terms was reimplemented as a term rewriter when namespaced terms was introduced in ifupdown-ng 0.10. Alpine still uses the legacy bonding scripts for 3.13, so we need to handle the rewritten term as well here. Fixes #12319.
