  Properly exit if GRUB installation fails

For example when partition table is GPT but grub installation
expects a MS-DOS partition table, then grub-install fails
but grml-debootstrap ignored this. Since the system isn't bootable
then this might go unnoticed, so properly fail as soon as grub-install
returns with exit code != 0.
