[baseimage]: /host unmount timeout issue during reboot. (#5032)

Fix for the host unmount issue through PR #4558 and #4865 creates the timeout of syslog.socket closure during reboot since the journald socket closure has been included in syslog.socket

Removed the journal socket closure. The host unmount is fixed with just stopping the services which gets restarted only after /var/log unmount and not causing the unmount issues.
