color_buffers[] is currently hard coded to 3 for android which fails
in droid_window_dequeue_buffer when ANativeWindow creates 4 color_buffers
on ChromeOS while querying buffer age during dEQP partial_update tests.

Fixes dEQP-EGL.functional.partial_update* tests on chromebooks with
enabling EGL_KHR_partial_update.

v2: update comment instead of removing (Eric Engestrom)

Fixes: 2acc69da8ce "EGL/Android: Add EGL_EXT_buffer_age extension"
