Add support for OpenGL ES to egl-helpers. Wire up the new option for egl-headless and gtk UIs. egl-headless actually works fine. gtk hits a not-yet implemented code path in libEGL when trying to use gles mode: libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering. (This is mesa 17.2.3).
