[lldb][examples] Use Python3 versions of types module in performance.py

2.x had ListType and StringTypes (https://docs.python.org/2.7/library/types.html),
3.x removed these (https://docs.python.org/3.0/library/types.html).

We can use "str" and "list" directly as in 3.x all strings are
just "str", and ListType was always an alias to "list".
