d/tests: extend test coverage
- run superficial test for "rsync -h"
- run more upstream tests by adding acl and attr as build dependencies and running upstream tests as non-root and root user
- add Debian-specific local rsync tests which can also be run over an ssh connection
(cherry picked from commit 0c489ff3fc535030a19403fdc7a139b73791e910)
