xwayland: add envvar XWAYLAND_NO_GLAMOR

Browse Source 
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 to disable glamor support
in Xwayland.
