Subject: [PATCH] systemctl: don't update the reboot parameter if none is given

Otherwise systemd-reboot.service will remove the parameter that was set
before. This was broken in commit "b986229efe2cc96157aa14c37bab7843311bbef1
systemctl: bugfix for systemctl reboot command with argument"

(cherry picked from commit c31c4324c5120d9b38f8a5e39623c8242ee001e0)
