iscsi: Adapt package names for SUSE installations

When attempting to install iSCSI initiator and target packages on SUSE, it was observed that the test suite was failing due to incorrect package names.

Specifically, SUSE utilizes open-iscsi for the iSCSI initiator, as opposed to iscsi-initiator-utils.
Similarly, the SCSI target utilities on SUSE are provided by the tgt package, not scsi-target-utils.

This commit introduces a conditional check for SUSE distributions to ensure the correct iSCSI initiator (open-iscsi) and target (tgt) packages are selected and installed, thereby resolving installation failures on SUSE systems.

NOTE: This PR has already been merged in upstream.
