In CentOS/RHEL 8 there is no scsi-target-utils package, nor is it
available in EPEL. In RHEL 7 and beyond the LIO kernel subsystem can be
used instead of the tgtd daemon.
This change removes support for the SCSI target daemon on CentOS/RHEL 8.
The 'tgtd' image is no longer available for CentOS/RHEL 8.
