docs: sphinx-build-wrapper: allow -v override -q

Documentation builds were using "-q" for a long time, but sometimes
it is nice to see the Sphinx progress, without increasing build
verbosity - which would also turn on kernel-doc verbosity.

Instead of doing that, let's parse the sphinx-build already-existing
-v: each time it is used, it increases the verbosity level.

With that, if the default is to use -q, a single -v will disable
quiet mode. Passing more -v will keep increasing its verbosity.
