Bug#694495: grub2: avoid updating when in chroot

[Hector Oron]

Hello,

>   When attempting to generate x86 images, linux kernel tries to run grub hook and fails:

  Let me clarify the error log does not correspond with the fix. The
error log can be solved by debconf preseed, but I did have problems
with linux grub hooks and I had to apply previous patch.

  Let me know if you need further information.

regards,
