[PATCH 5/7] update.sh: Update to migrate rrd directories for collectd-5.x

[Adolf Belka <adolf.belka@ipfire.org>]

- Not tested by myself but it uses the same code as in the backup.pl changes which were
   tested and worked. So expectation is that they will work in the Core Update but this
   will be able to be evaluated when the Testing Release is issued.
