Since commit8d3e4ac7cd("scope: refuse activation of scopes if no PIDs to add are left") all "systemd-run --scope --user" calls fail because cgroup attachments delegated to the system instance are not counted towards successful additions. Fix this by incrementing the return value in case unit_attach_pid_to_cgroup_via_bus() succeeds, similar to what happens when cg_attach() succeeds directly. Note that this can *not* distinguish the case when unit_attach_pid_to_cgroup_via_bus() has been run successfully, but all processes to attach are gone in the meantime, unlike the checks that commit8d3e4ac7cdadds for the system instance. This is because even though unit_attach_pid_to_cgroup_via_bus() leads to an internal unit_attach_pids_to_cgroup() call, the return value over D-Bus does not include the number of successfully attached processes and is always NULL on success. Fixes: #21297
