Use systemctl reload in logrotate script

In 5f74814 (Use systemctl for sending SIGHUP to the service,
2015-06-29), a direct call to `kill` was replaced with `systemctl kill`.

This can be simplified using `systemctl reload` instead.  Doing so also
resolves an issue when `POSIXLY_CORRECT` is set (rhbz#2124488).
