Use flips for back- and fake front buffers.
This might lead to fake front and real front being shared if the hardware
is page-flip capable.
In any case it will save a full-drawable copy and also the subsequent wait for
the X server to submit that copy to hardware if front-buffer reading or
rendering is enabled.

This will actually break even more the already broken eglSwapBuffers()
with EGL_BUFFER_PRESERVED on the x11-dri3 platform. I'm working on a
follow-up patch, though that should fix it.
