[PATCH] Testcase for checking lvm module

[BVK Chaitanya]

Hi,


Attached patch adds a testcase to check for GRUB's lvm module
functionality.  It configures lvm volumes on-the-fly on temporary disk
images, and tests to see whether grub-shell ls command identifies them
or not.

Since all of the LVM operations need root privilege, this real test is
performed only when it is executed as root (or sudo make check); test
simply passes otherwise.  In future we may add sudo-check Makefile
target to execute these type of tests automatically sing "sudo"
feature.
