[cogl/wip/android: 6/12] gles1: Include GLES/egl.h or EGL/egl.h depending on the implementation



commit 8dc147a3dcc916d5b37efa58ae37ca917e45ef41

    gles1: Include GLES/egl.h or EGL/egl.h depending on the implementation
    
    Early implementations provided only a GLES/egl.h while Khronos's
    implementer guide now states EGL/egl.h is the One. Some implementations
    keep a GLES/egl.h wrapper around EGL/egl.h for backward compatibility
    while others provide EGL/egl.h only.
    
    Also took the opportunity to factorize a bit this inclusion in
    cogl-defines.h.
