dns: remove default 8.8.8.8 DNS server

Now that DNS servers are pulled in from the DHCP config,
this is unnecessary. Moreover, it's harmful: getaddrinfo will
attempt to reach 8.8.8.8 before DHCP has completed. This
can result in the DNS client keeping a UDP endpoint with
a bad source IP address open for many seconds, blocking a
real connection.

Without 8.8.8.8, getaddrinfo immediately fails before
DHCP because there are no known DNS servers. It does not
try to make a connection until the real local IP is setup.
