Fix broken FTP tests where timeouts started recently

* FTP tests are failing and one possibility is that a recent set of new images for ftpd image have caused us problems * #1580 is one failed attempt * could be down to an upgrade in dependency libs too but the tests started failing around a time when no obvious upgrades related to FTP happened * in short term, I think we need to disable the broken tests to keep the build clean ``` [info] FtpExamplesSpec: [info] a file USER ******* 331 User username OK.
