Bump socket.create_connection() timeout to 10 seconds

The tcp Pytest on OpenBSD fairly reliably fails when receive_tcp()
on a socket is attempted:

    >           (response, rtime) = dns.query.receive_tcp(sock, timeout())

    tests-tcp.py:50:

    /usr/local/lib/python3.9/site-packages/dns/query.py:659: in receive_tcp
        ldata = _net_read(sock, 2, expiration)
    _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

    sock = <socket.socket [closed] fd=-1, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6>
    count = 2, expiration = 1662719959.8106785

        def _net_read(sock, count, expiration):
            """Read the specified number of bytes from sock.  Keep trying until we
            either get the desired amount, or we hit EOF.
            A Timeout exception will be raised if the operation is not completed
            by the expiration time.
            """
            s = b''
            while count > 0:
                try:
    >               n = sock.recv(count)
    E               socket.timeout: timed out

This is because the socket is already closed.

Bump the socket connection timeout to 10 seconds.
