contrib: remove extraneous cruft

We don't want people packaging these or even using these scripts, which
are only useful for limited development circumstances, so get rid of
them. More widespread development testing techniques still exist in
src/debug.mk and src/netns.sh

+                === IMPORTANT NOTE ===
+
+Do not use these scripts in production. They are simply a
+demonstration of how easy the `wg(8)` tool is at the command
+line, but by no means should you actually attempt to use
+these. They are horribly insecure and defeat the purpose
+of WireGuard.
+
+                     STAY AWAY!
+
+Distros: do not distribute these with your packages.
+
+
+
+That all said, this is a pretty cool example of just how
+darn easy WireGuard can be.
