Fix ephemeral devices on LVM don't get mkfs'd
Fixes bug 1083424
Updated imagebackend to run the necessary callback conditionally
based on whether LVM is configured for use and ephemeral_size is
defined. The callback function was updated not to invoke qemu-img
for LVM, since the ephemeral disk is already present/created via
LVM. Lastly, the mkfs call had to be changed to be run as root,
since we are dealing with raw devices.
