docs: conf.py: rename some vars at latex_documents logic

Currently, the logic uses fn and doc vars, but they don't
properly describe what such vars do.

Make them clearer:
	- fname: points to the file name to search (index.rst);
	- doc: contains the name of the LaTeX or PDF doc to
	  be produced.

With that, the checks for SPHINXDIRS and for subdirs will
be more coherent.
