lib/wind: PY3 gen-punycode-examples.py

Browse Source 
Update gen-punycode-examples.py for python 3.

gen-punycode-examples.py parses the Sample strings from section 7.1
of rfc3492.txt and generates the punycode_examples.[ch] sources containing
the punycode_examples[].

Python 3 requires that print output be surrounded by parentheses
and the split and join operations have been moved from the "string"
class to built-ins.

This change adds the missing parentheses and switches to the built-in
split and join str operations.

The "string" class is no longer required as an import.
