fix decoding of utf-8 chars in yaml test

Python 3 would fail to load yaml from doc/examples/cloud-config-apt.txt
when the LANG (specifically LC_CTYPE) was 'C'.

The changes here do 2 things:
 a.) remove the non-ascii characters from the yaml file.
 b.) fix the validate-yaml.py program to decode using utf-8 specifically
     rather than using the inherited settings.

This fixes it now for ascii and in the future also should non-ascii slip in.
