[meta-oe][PATCH] opencv: remove setup_vars_opencv4.sh

[<mingli.yu@windriver.com>]

From: Mingli Yu <mingli.yu@windriver.com>

Currently opencv ships with setup_vars_opencv4.sh, but there comes below
error:
 # /usr/bin/setup_vars_opencv4.sh
 Setting vars for OpenCV 4.5.2
 Append PYTHONPATH: /usr/bin/../lib/python3.9/site-packages
 # ls /usr/bin/../lib/python3.9/site-packages
 ls: cannot access '/usr/bin/../lib/python3.9/site-packages': No such file or directory

Considering the file is useless and also removed in other distribution [1],
so remove the file to avoid confusing.
