fdio noha: Workaround tap MAC generation issues

systemd 230..241 has issues generating persistent MAC addresses
for bridge/tap/etc network devices, causing trouble for VPP agent
hooking tap devices to the bridges it creates on the fly.

Work around this by disabling the faulty policy, as suggested in [1].
