Since I reckon Perl 5.14+ is pretty common, favoring the
bundled Socket.pm is advantageous in reducing installation
overhead and memory use, since we already rely on "Socket"
being loaded.

We need to keep Unix-socket-only httpd instances working
without Socket6. This fixes t/httpd-unix.t with Socket6
uninstalled.

Users on Perl 5.14+ are common, so we can try the bundled Socket
(not "Socket6") module before attempting Socket6 for IPv6.
