XCP pygrub should have ext4 support.

It currently doesn't because the libfsimage ext2fs-lib module is linked against libext2fs, which doesnt have ext4 support in XCP.

Instead, XCP should use the ext2fs module that comes with libfsimage, which has ext4 support.

Most new releases of distributions has it as their default filesystem. Most notably, Ubuntu 10.04

An easy way for the build to use ext2fs instead of ext2fs-lib, is to not have ext2fs/ext2fs.h present.

Alternatively this patch hard codes it.
