test(fuzz): esp_netif/ping_sock/ip_addr stubs — un-break ADR-061 fuzz build after #954

csi_collector.c gained esp_netif.h / ping/ping_sock.h / lwip/ip_addr.h includes for the #954 gateway self-ping; the host-fuzz stub env lacked them, breaking the fuzz build on main since 5789351b7. Stubs return no-gateway so the self-ping path early-outs (compiles + links, never exercised — matches the fuzz threat model which targets frame serialization, not the network stack).
