rsync all files/dirs in a single command

Previously, DLRN ran several rsync commands to transfer the contents
of the hashed repo and some other files (current symlink, report.html)
to the backup server. We can combine them in a single transfer.

This fixes https://github.com/openstack-packages/DLRN/issues/23
