gles1: Include GLES/egl.h or EGL/egl.h depending on the implementation

Browse Source 
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.
