[Buildroot] I: Configure buildroot for xen

rootfs.cpio and rootfs.tar generated by Buildroot contain the same
thing: the root filesystem generated by Buildroot.

I believe the xen-create-image --initrd option is to pass an initrd
that is not the root filesystem, such as what is done typically in
Linux distributions, where the initrd contains a temporary root
filesystem used to load the appropriate kernel modules and device
firmwares to make the system operate, before switching to the real root
filesystem.

So just get rid of --initrd=rootfs.cpio, I think it should work. It
will directly mount the ext3 filesystem as your root filesystem and
that's it.

Best regards,

Thomas
