Install mesa-libgl binary for opencv supportability.

[harshad16]

Users, install opencv on runtime, are unable to use the package, as it requires os binary mesa-libgl in the os for the proper execution of the tools. Example:
when try to use the ultralytics, the following error would be thrown for the opencv.

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Suggestions:

Install the mesa-libgl binary in the base image:

USER root
RUN yum install mesa-libGL -y
USER default

WorkAround

Users can install opencv-contrib-python-headless==4.8.0.76 python package to make the use of opencv
