Fix OpenGL initialization when OpenGL and OpenGLES are both available.

Browse source 
Both options default to "yes" via configure, and having libs/headers
for both installed is not unusual.

We default to OpenGL on this compile time combination, but can enforce
OpenGLES via setting the envvar SDL_VIDEO_X11_GLES.
This will be further refined based on community feedback.
