Not all compositors allow for customizing the Xwayland command line,
gnome-shell/mutter for example have the command line and path to
Xwayland binary hardcoded, which makes it harder for users to disable
glamor acceleration in Xwayland (glamor being used by default).
Add an environment variable XWAYLAND_NO_GLAMOR t odiable glamor support
in Xwayland.
