hellogles3: Request core profile context

Browse Source 
...instead of compatibility, in order to play nice with systems
that have no compatibility profile support (macOS). Instancing
needs OpenGL 3.x so sticking with 2.x contexts is not an option.

The example looks fully compatible with core profile so its
functionality should not change.
