Subject: [PATCH] utils: add new gdm-disable-wayland binary
We currently disable wayland for cirrus by calling printf
from a udev rule. This works, but it's a little too open
coded to easily write SELinux policy for.
This commit introduces a new program, gdm-disable-wayland,
that does the same thing, but in a dedicated binary.
A future commit will change the udev rule to use the binary.

(cherry picked from commit 2dc57da31781dedfe374ce353b0f5fd6aa9da56f)
