grub2: fix a few minor issues in help text
The help text of grub2 explains the detailed steps to create a disk
image with grub2 installed on it. However, the steps for the
BIOS-based systems have a few minor issues fixed by this patch:
- When calling partx to get the partitions detected, we should do it
on the /dev/loop0 block device, and not on the underlying disk.img
image file.
- The grub-bios-setup utility must be called as root to work properly
on /dev/loop0.
- The steps to cleanup the partx and loop device were missing.
