[BrowserKit] Cookie expiration at current timestamp

In `Symfony\Component\BrowserKit\Cookie` a cookie is expired if the `expires` timestamp is in the past. I would like to change it to also be expired if the `expires` timestamp equals the current exact timestamp. This would still be in line with [RFC 6265](https://tools.ietf.org/html/rfc6265#section-4.1.2.1), as it states `The Expires attribute indicates the maximum lifetime of the cookie, represented as the date and time at which the cookie expires`.
Reason for this change: Cookies usually both have `expires` and `Max-Age` set, and Symfony sets `Max-Age` to zero if a cookie is expired (in `Symfony\Component\HttpFoundation\Cookie`). When converting cookies between string and object representations, `Max-Age` is the preferred source of truth for the expiration, but `Max-Age` set to zero is converted to an `expires` timestamp at this exact second, currently making the cookie not expired in `Symfony\Component\BrowserKit\Cookie`, even though it should be.
I noticed this discrepancy in my tests when checking if a cookie no longer existed after deleting it, yet it was still there, because `Cookie` thought it would only expire after the `expires` timestamp had passed. I am also thinking of raising an issue for `Symfony\Component\HttpFoundation\Cookie`, as importing and exporting an expired cookie (via strings) changes the `expired` value. I thought this change was a simpler one for now, and should have no negative/unexpected impact.
