eglfs: Prevent printing a warning in every widget-based app 

Attempting to reflect reality with the value of AA_ShareOpenGLContexts
was a valiant attempt, but it is not possible to do setAttribute without
getting a warning now once QGuiApplication is constructed. So just leave
the attribute as is, changing its value is not strictly required.

Fixes: QTBUG-85796
Pick-to: 5.15
