borg-backup: randomise time on a per-server basis

Browse Source 
Currently this randomises the minute based on a seed generated from
the backup server name; i.e. all hosts going to a particular backup
server get the same minute.  Use the inventory_hostname of the host
actually being backed up as the seed; this will distribute the backups
over the hour as originally intended.
