Subject: [PATCH] services: sddm: Disable wayland display-service

* gnu/services/sddm.scm (<sddm-configuration>): wayland is not walid value of
display-server.

(sddm-configuration-file): do not use sddm-configuration-display-server at the
moment, for user config: (display-server "wayland"), will let user's addm show
blank screen when sddm update to 0.20.

* doc/guix.texi (X Window): update display-server doc of sddm-service-type.
