[client] egl: RGB24 improvements

Browse Source 
This patch performs several changes.

* Alters the fourcc codes to types that ignore the alpha channel where
  possible to allow the gpu to internally use 24-bit formats.
* Attempts to use DRM_FORMAT_RGB888 first as some GPUs may support this
* If DMABUF is not in use the data is now imported directly as RGB24
  without the post-processing shader
