Warn if you're running against an XWayland server

Because there's a 99% chance you don't want this.

Xwayland is an X server that uses a Wayland Compositor as backend.
Xwayland acts as translation layer between the X protocol and the Wayland
protocol but does not have direct access to the hardware. The X Input
Extension devices created by Xwayland ("xwayland-pointer",
"xwayland-keyboard", etc.) map to the Wayland protocol devices,
not to physical devices.
These X Input Extension devices are only visible to other X clients
connected to the same Xwayland process. Changing properties on Xwayland
devices only affects the behavior of those clients. For example, disabling
an Xwayland device with xinput does not disable the device in Wayland-native
applications. Other changes may not have any effect at all.
In most instances, using xinput with an Xwayland device is indicative of a
bug in a shell script and xinput will print a warning. Use the Wayland
Compositor's native device configuration methods instead.
