services: shepherd: Do not unload transient services.
Fixes <https://issues.guix.gnu.org/54812>. Starting with Shepherd 0.9.0 and the use of 'make-inetd-constructor' in commit 808b9e850491c7b1d867a5f1f4d5ee6f61f345d4, systems might be running transient Shepherd services such as those corresponding to SSH connections. Before this change, 'shepherd-service-upgrade' would have those transient services in the list of services to unload; concretely, that would lead all SSH connections to be closed upon 'guix system reconfigure'. * gnu/services/shepherd.scm (shepherd-service-upgrade): Remove transient services to TO-UNLOAD.
