    cbfstool: Fix build error with clang when comparing enum
    
    If HOSTCC=clang, the -Wtautological-constant-out-of-range-compare is
    set automaticaaly. That assume the value of type enum is in the defined
    range. Then testing if a type enum is out of range causes build error.
    
    Error:
    coreboot/util/cbfstool/cbfs_image.c:1387:16: error:
     comparison of constant 4 with expression of type 'enum vb2_hash_algorithm'
     is always false [-Werror,-Wtautological-constant-out-of-range-compare]
     if (hash_type >= CBFS_NUM_SUPPORTED_HASHES)
        ~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~~~~~~~
