shared/install: handle dangling aliases as an explicit case, report nicely
This fixes 'preset-all' with a unit that is a dangling symlink.
$ systemctl --root=/ preset-all
Unit syslog.service is an alias to a unit that is not present, ignoring.
Unit auditd.service is masked, ignoring.
Unit NetworkManager.service is masked, ignoring.
