Finalize CSIT script regardless of setup success

Finalize CSIT script regardless of setup success

 - run teardown and env info collection steps always on exit
   regardless of any potential failures in previous steps
   (particularly setup)
 - Note that this puts an implicit requirement on project-specific
   teardown scripts to be able to do their job even if some setup steps
   have failed!
 - add trivial sdc-dcae-d change to trigger CSIT verify job
