Increased minimum required Socket version from 1.3 to 2.016

This turned out to be the cause of the remaining problem on CPAN RT#100020,
but only on machines having IO::Socket::IP (and even then that worked fine
on my machine, so it is probably OS dependent).

Don't restate the minimum required version everywhere that Socket is used.
It seems like overkill (and maintenance hassle) in a world where various
CPAN shells do a good job of installing required versions of prerequisite
modules, and it already wasn't done for IO::Socket (which also has a minimum
required version).

+    - Increased minimum required Socket version from 1.3 to 2.016.  This may be
+      required when those modules that can support IPv6 load IO::Socket::IP (on
+      some OSes, at least).  It does not appear to be necessary if they load
+      IO::Socket::INET6 or IO::Socket::INET instead, but this is not easy for
+      the end-user to control so it is simpler to always insist on Socket 2.016
+      or higher.  [CPAN RT#100020]
+
     - Fixed "Argument ... isn't numeric in subroutine entry" warnings when using
       older versions of Perl.  [CPAN RT#100020]
