emulator: repoint dev-rig confs to the current NIC (realnic F70BADD7A)

The old Network Bridge adapter (DB5521D) no longer exists on the dev rig;
pcap now binds the physical Realtek directly. Update the tracked rendered
confs so a networked launch from the repo tree reaches the host. Symptom of
the stale value was the guest looping "NO PACKET DRIVER FOUND" (pcap open
fails -> NE2000 absent -> ODI stack can't bind). net_diag.conf left alone
(unrelated pre-existing churn).
