    sbin/newfs_hammer: Allow 0 for boot_area/memory_log size [3/3]
    
    This commit gives an option to allocate no space for
    boot_area/memory_log since these aren't used for anything.
    
    Allow boot_area/memory_log size smaller than HAMMER_{BOOT,MEM}_MINBYTES
    if -f is specified. If -f is not specified, MINBYTES are still
    low limits for boot_area/memory_log.
    
    This is similar to the way newfs_hammer allows undo size smaller
    than 512MB when -f is specified.
