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. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
