[PATCH] grub-shell: Use shell variable instead of autoconf

[Glenn Washburn <development@efficientek.com>]

By using shell variable that are set once by the expansion of an autoconf
variable, the resulting shell script is more easily moved and modified
from the build/install directory it was generated for. The resulting
script is more readable as well.
