Set HOME to private /tmp for borgbackup

Browse Source 
borg writes to $HOME/.config but in our case it also works on $HOME (/var/vmail).

This could cause the following error when running the backup: file changed while we backed it up

This commit fixes it by setting HOME to private /tmp for borg.
