reproducer script

I recently came across a strange grub2-install error when building kiwi images
in OBS.

The reason is a bug in the minix file system detection.
I filed upstream bug https://savannah.gnu.org/bugs/index.php?57652

Note I experienced this on SLES15-SP1.
The bug is still present in current Tumbleweed (see attached reproducer script)
This bug thus needs fixing in all supported openSUSE releases.

The reproducer-script is called as root like

# bash ./grub-bug-57652-reproduce-suse.sh /tmp/grub-test.img /mnt

/tmp needs 1GB of free storage to store the image.
