services: Consistently use SDDM rather than GDM on non-x86_64.

This is a follow-up to 49599fab56.

Fixes: <https://issues.guix.gnu.org/52908>.

* gnu/services/xorg.scm (set-xorg-configuration)[login-manager-service-type]:
When the current system or target system begins with the string "x86_64", use
gdm-service-type as before; otherwise, use sddm-service-type.
* gnu/system/examples/vm-image.tmpl (services): Add sddm-service-type to the
list of service types to remove.
