Dns.GetHostEntry no longer returns hostname

Original bug claimed that it broke in Mono 4.0.
I've tested on 5.8.0.22 (Gentoo) and can reproduce the issue.

// Works for any IP you wish to test
// IP for google.com
var google = Dns.GetHostEntry("216.58.216.14");
Console.WriteLine("Hostname: " + google.HostName);
// outputs: "216.58.216.14" instead of "google.com"

This is a particular problem in my use case for an IRCd where DNS lookups of IPs are common for bans (like DNSBLs) or allowing/disallowing ISPs or services.
