Generate static loopback.cfg configuration without depending on GRUB's regexp module

The GRUB version provided by Debian/squeeze sadly doesn't support
the regexp module yet.  Therefore we can't use the file globbing
pattern to include configuration files.  So instead build a somewhat
more static loopback.cfg configuration file when generating the ISO.
