binary_loopback_cfg now renders grub.cfg by default.

The binary parts of grub-pc are left for the original binary_grub-pc.
As a consequence both /boot/grub/grub.cfg and /boot/grub/loopback.cfg files will be present in any Debian Live CD.

This might be useful to be reused from binary_grub-* bootloaders.
