specify `socktype' option for getaddrinfo() to get predictable result

Today Adura on #mojo found that Mojolicious can't pass tests when Net::DNS::Native installed on Windows with strawberry perl: http://irclog.perlgeek.de/mojo/2014-12-16#i_9813122
Tracking it down showed that problem starts from ... my favorite IO::Socket::IP
This test script always showed "can't connect in 10 sec"

```Perl
use strict;
use IO::Socket::IP;
use Socket 'IPPROTO_TCP';
use IO::Select;

my ($err, @res) = Socket::getaddrinfo("www.google.com", 80, {protocol => IPPROTO_TCP});
die $err if $err;

my $ip = IO::Socket::IP->new(Blocking => 0, PeerAddrInfo => \@res) or die $@;
my $sel = IO::Select->new($ip);
$sel->can_write(10) or die "can't connect in 10 sec";

warn "Connected!";
```

Some debug showed that getaddrinfo() on this Windows box always returns resolved address with `socktype' flag equals to 0, but for TCP protocol this flag should be SOCK_STREAM=1.
So changing flags for getaddrinfo to {protocol => IPPROTO_TCP, socktype => SOCK_STREAM} fixes the problem
