Subject: [PATCH 4/5] Create and configure the missing CHRP boot script.
From: Frank Scheiner <frank.scheiner@web.de>

Message-id: <[🔎] 9d14089b-5887-cf65-464a-dd9e6f159a69@web.de>
Instead of the `ofpathname` tool (which is used in `grub-install`
internally), the `ofpath` tool is used to get the OF path of the used
OFFS partition, as this was the only tool that produced a usable/working
output on the tested machines (PowerMac11,2 and 7,3). We can omit the
creation of the CHRP script as soon as the base template for it ([1]) is
shipped with the `grub-ieee1275-bin` package. From then on it only needs
to be reconfigured until `grub-install` gets the correct OF path.

The case clause is placed after the package version of GRUB is
determined, as it is "needed" (but not vital) for the CHRP script, but
before the call to `grub-install`, as this fails if this file is not
available at the expected location.
