Covers the SCM_RIGHTS fd-passing path end-to-end against a real QEMU: open an eventfd, hand it off via QMP_CLIENT_ARGS_FD() on the very first qmp_client_invoke() against a fresh client, and verify QEMU's add-fd reply carries the expected fdset-id. Complements the mock-based unit test with an authoritative check that QEMU actually consumes the fd from its FIFO receive queue when processing the command — the AF_UNIX kernel behaviour around non-scm skb absorption into following scm-bearing recvs is real-traffic-shaped rather than mock-shaped.
