KVM test: Updating tests_base.cfg with cdrom_cd1

The latest cdrom patch from michael stablishes cdrom_cd1 as the first cd used by vms, but in all unattended installs we use only cdrom, which makes it to not honor the index set to it. Let's define cdrom_cd1 index to be 1, and change all cdrom entries to cdrom_cd1. Also, update the unattended install script to retrieve the cdrom from the environment variable cdrom_cd1 instead of cdrom.
