Py3'ify some of the examples that get run at startup.

Even though these are under examples/, they actually get loaded
when LLDB starts up during initialization of ScriptInterpreterPython.
There's obviously some kind of layering issue here (and comments
in the code even point to that as well), but for now just make them
py3 compatible.
