This change set, addressing [8344856](https://bugs.openjdk.org/browse/JDK-8344856), removes `SecurityManager` and friends from `sun.net.FtpURLConnection`. This is the only leftover from `SM` cleanup in the subclasses of `URLConnection` in the `sun.net` package. Successful `tier1..3` CI runs on b02813b048ec63479c49e74ca6326a00409dd34f are shared in the ticket.
