units: remove RefuseManualStart from units which are always around In a normal running system, non-passive targets and units used during early bootup are always started. So refusing "manual start" for them doesn't make any difference, because a "start" command doesn't cause any action. In early boot however, the administrator might want to start on of those targets or services by hand. We shouldn't interfere with that. Note: in case of systemd-tmpfiles-setup.service, really running the unit after system is up would break the system. So e.g. restarting should not be allowed. The unit has "RefuseManualStop=yes", which prevents restart too.

core: --user -- add basic.target an sort against it like --system does
