Issue Description:

Current Behavior:

When I make a network request using `URLSession` while running some code that is compiled and run through the XCode ecosystem, the cookies returned by the request are automatically stored and available. However, when I run the same Swift code on an Ubuntu docker image, the cookies returned by the response are not saved automatically. The cookies do come back from the server as I was able to print their values after the network response came back, but, they don't get stored. As a workaround, I explicitly tried to write to the local data store by calling `HTTPCookieStorage.sharedCookieStorage(forGroupContainerIdentifier: <name>).setCookie(thisCookie)`. However, even after I did this, the cookie value got cleaned while making the subsequent network request.

Expected Behavior:

URLSession's Cookie handling logic for Linux needs to be consistent with iOS and MacOS.
