The preserved swap behavior is currently untested in piglit and not supported
on the GLX side. Before working on implementing it for EGL/DRI3, let's
disable it until support comes.
This patch is trivial enough and will likely be squashed in the commit
egl/x11: Implement dri3 support with loader's dri3 helper
