dhcp: move filtering of bogus DNS/NTP addresses out of DHCP client
The DHCP client should not pre-filter addresses beyond what RFC
requires. If a client's user (like networkd) wishes to skip/filter
certain addresses, it's their responsibility.
The point of this is that the DHCP library does not hide/abstract
information that might be relevant for certain users. For example,
NetworkManager exposes DHCP options in its API. When doing that, the
options should be close to the actual lease.
This is related to commit d9ec2e632df4905201facf76d6a205edc952116a
(dhcp4: filter bogus DNS/NTP server addresses silently).
