nfsd/fstests: fix pNFS block layout iSCSI configuration

For pNFS block layout testing, the NFS server must run the iSCSI
target service. Fix the Ansible role execution by:

1. Remove invalid delegate_to from include_role in fstests role
2. Add iSCSI target setup to nfsd role when pNFS is enabled
3. Keep iSCSI initiator setup with correct target hostname

The iSCSI target now runs on the NFS server itself, and test
nodes connect to it as initiators for pNFS block layout access.
