Evas filters: Fix glReadPixels usage for EGL 

This is a simplified version of the patch in master:

commit 7a614c80f3

    Evas filters: Fix glReadPixels usage for EGL

    EGL might very well not support RGBA read mode, so we
    need to check for it first.

    Also remove some error logs (see previous commit), and useless
    initialization of the Evas GL engine.
