Fix container creation time in test/builders
Fix container creation time in test/builders

The created time of the containerd is initialized with nanoseconds,
it seems to be a mistake.

In other places of the code, this field is initialized with seconds:

    $ grep -rh 'time\.Now()\.Unix()' | grep Created
    Created: time.Now().Unix(),
    Created: time.Now().Unix(),
    return []image.HistoryResponseItem{{ID: img, Created: time.Now().Unix()}}, nil

We can also see the the formatter assumes it to be seconds:

    cli/command/formatter/container.go
    ----
    func (c *ContainerContext) CreatedAt() string {
        return time.Unix(c.c.Created, 0).String()
    }

Interestingly, initializing the field with nanoseconds seems to work,
except on mips architecture, where it causes some kind of overflow.
