Subject: Live image should honor DNS servers from DHCP

Package: devuan-installer
Version: 3.1.1

When I boot the devuan live system[1] it ignores the DNS servers
provided by DHCP and uses google servers instead. The expected
behavior is for the system to use DNS servers provided by DHCP instead
of pinging google.

Running
# dhclient eth0
from the live system sets the DNS servers to those provided by DHCP,
as expected.

Here's a transcript demonstratig the values embedded in the iso:
# mount devuan_beowulf_3.1.1_amd64_desktop-live.iso /mnt/iso
# mount /mnt/iso/live/filesystem.squashfs /mnt/squashfs
# cat /mnt/squashfs/etc/resolv.conf
## google's nameservers
nameserver 8.8.8.8
nameserver 8.8.4.4

The system configures IP, route, etc. from DHCP as expected.
