docs: conf.py: only use CJK if the font is available
If we try to build a book with asian characters with XeLaTeX
and the font is not available, it will produce an error.
So, instead, add a logic at conf.py to detect if the proper
font is installed.
This will avoid an error while building the document, although
the result may not be readable.
