scripts: sphinx-pre-install: fix a bug when using with venv
When python3 creates a venv, it adds python into it!
This causes any upgrade recommendation to look like this:
/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
With is wrong (and it may not work). So, when recomending
an upgrade, exclude the venv dir from the search path, and
get the system's python.
