    sys/vfs/hammer: Remove signature from ondisk node
    
    The node signature was added in the early stage of hammer
    development, but it's no longer used for anything except
    that newfs_hammer sets the field to GOOD (for no reason).
    
    c461935c added some code to propagate the GOOD signature
    on node split (just to make it look a bit more sane), but
    it's useless anyway.
    
    This commit changes the signature field to reserved00,
    and also gets rid of HAMMER_BTREE_SIGNATURE_XXX macros.
    The change doesn't affect anything just like c461935c did
    nothing good or bad.
