dev-python/sshtunnel: re-enable tests

The patch removing server support lead to bug 683774, so to fix the
tests you just require that flag. Still include a patch that fixed the
deadlock as its still a real bug that it gets stuck in that while loop.

+Subject: [PATCH] Try to remove defunct threads from running_threads just in
+ case
+
+On Gentoo it was decided to remove server functionality from
+paramiko leading to the ssh-server to be dead before it could be
+properly removed from running_threads. This would lead to a hang where
+memory footprint of the process would grow with repeated "thread
+ssh-server now stopped" messages inevitably leading to an OOM condition.
+
+So try to remove defunct threads from running_threads after the fact to
+stop this problem from coming back and let it fail normally.
