    x86: Preinitialise all modules to be of kind BOOTMOD_UNKNOWN
    
    A later patch removes boot_module and replaces its uses with bootmodule.
    The equivalent field for "type" doesn't have BOOTMOD_UNKNOWN as a zero
    value, so it must be explicitly set in the static xen_boot_info.
    
    Not a functional change.
