m/n/core/network/dhcp4c: fix logic bug in DNSServers

This previously accepted all non-undefined (0.0.0.0) IPs as servers on
account of the `|| ip4Num != 0` in the condition. That's unnecessary
anyways, so let's drop it.
While we're in there I also changed the deduplicating map from a
map[uint32]struct{} to a map[uint32]bool, making the code a bit shorter.
