Subject: [PATCH] Fixed incorrect path to the grub-btrfs.cfg file in Grub menu
 (#79)

Fix #72
The submenu generated by "grub-btrfs" doesn't load in the "GRUB menu."
Sometimes the Grub prefix and root variable don't match.
This ensures that the prefix variable is used to load the grub-btrfs.cfg file.
See
How to specify files
and
Special environment variables : root
and
Special environment variables : prefix
