I tested this patch with the included vm image, using the following
script. After logging in, 'ntpctl -s all' shows openntpd connecting to
the ntp servers and updating the time.

/.$(./pre-inst-env guix environment guix -- ./pre-inst-env guix system vm ~/vm-image.scm) -m 768 -device e1000,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:53
