[PATCH 04/13] fstests: fix pNFS block layout iSCSI setup

For pNFS block layout testing, the NFS server needs to provide
block storage via iSCSI. Fix the setup by:

1. Setting up the iSCSI target service on the NFS server itself
2. Overriding iscsi_target_hostname to point to the NFS server
   when setting up iSCSI initiators on test nodes

This allows pNFS block layout testing without requiring a
separate dedicated iSCSI target host.
