component/rdiff-backup/rdiff-backup-1.3.4-librsync-1.0.0.patch

+Patch by Roman Tereshonkov and Kari Hautio for rdiff-backup <= 1.2.8 to avoid a build failure with
+librsync >= 1.0.0 (which is a security bugfix release). The discussion and solution finding can be
+found at https://bugs.launchpad.net/duplicity/+bug/1416344 (for duplicity).
