logind: avoid a dot before parenthesis

systemd-logind[27]: System is rebooting. (Applied kernel updates.)

is changed to

systemd-logind[27]: System is rebooting (Applied kernel updates).

Users should not add a dot in the sentence in --message, i.e. the correct usage is now:
$ systemctl reboot --message "Applied kernel updates"
