Fix rsync after build
Fix rsync after build

The previous code may not use the -p ssh option correctly, and we
prefer to disable strict host key checking to avoid having to
login once with the ssh key before the initial dlrn run.

Also, we need to run rsync after the reports are generated, since
we are also syncing them.
