rsnapshot: add rsnapshot backup utility

this adds the rsnapshot backup utility to the packages feed.

To be compatible with busybox logger, I had to patch rsnapshot to don't
pass -i to logger. This package was also proposed in Ticket #11371, but
in a wrong categorie, without this patch, without most of the dependencies
and without the conffiles line to save rsnapshot.conf over sysupgrade.

+  rsnapshot is a filesystem snapshot utility for making backups of local and
+  remote systems.
+
+  Using rsync and hard links, it is possible to keep multiple, full backups
+  instantly available. The disk space required is just a little more than the
+  space of one full backup, plus incrementals.
