ImageMobject misses attributes when rendered with OpenGL

## Description of bug / unexpected behavior

When using adding an `ImageMobject` to a scene rendered with OpenGL, an error is raised about it missing the `should_render` attribute.

## Expected behavior

The missing `should_render` attribute should be added by `OpenGLImageMobject` and the error thus not thrown.

## How to reproduce the issue

Code for reproducing the problem

Run with `manim -pql main.py OpenGLImage --renderer=opengl`

```py
class OpenGLImage(Scene):
def construct(self):
self.add(ImageMobject("path/to/any/image"))
```

## Additional comments

Start by reproducing the issue with `manim -pql main.py OpenGLImage --renderer=opengl`, then inspect the OpenGL rendering path in `manim/renderer/opengl_renderer.py` and the mobject attribute handling shown in `manim/mobject/mobject.py`. Done means adding the missing `should_render` attribute for `OpenGLImageMobject` so the provided ImageMobject scene renders without the AttributeError.
