api: always add new CD drives to bootorder

Attaching an ISO image to a VM is usually/often done for two reasons:
* booting an installer image
* supplying additional drivers to an installer (e.g. virtio)

Both of these cases (the latter at least with SeaBIOS and the Windows
installer) require the disk to be marked as bootable.

For this reason, enable the bootable flag for all new CDROM drives
attached to a VM by adding it to the bootorder list. It is appended to
the end, as otherwise it would cause new drives to boot before already
existing boot targets, which would be a more grave (and IMO bad)
behaviour change.
