Don't build XComposite buffer integration by default
Both xcomposite-egl and xcomposite-glx have rendering issues, and they
do not work with the latest Nvidia driver versions.
These plugins were created to allow testing/debugging of QtWayland-based
compositors on desktops that did not support Wayland natively. At this
time, Wayland is much more widely supported on the desktop, and
[ChangeLog][Extensions][The xcomposite-egl and xcomposite-glx shell
extension protocols are no longer built by default.]
