[PATCH 1/5] Install hfsutils in-target for NewWorld Power Macs (adapted from d-i/yaboot-installer).

[Frank Scheiner <frank.scheiner@web.de>]

The installation of the hfsutils package is located in debian/postinst
similar to d-i/yaboot-installer, from which the code was adapted. But
d-i/grub-installer does all in-target installations from the
`grub-installer` script itself. If this is important this can still be
moved to `grub-installer`.
