dev-python/flask-cors: Use best_version instead of equery

To find the location of the installed python-docs.  Zero_Chaos suggested
the best_version approach on #gentoo-python just now.

The installed version of these docs may soon change, with the
python-docs package shifting to a per-slot naming scheme that more
closely matches the upstream Python naming scheme [1].
