    cbfstool: make endian detection code more robust
    
    Accessing the memory of a char array through a uint32_t pointer breaks
    strict-aliasing rules as it dereferences memory with lower alignment
    requirements than the type of the pointer requires. It's no problem on
    x86 as the architecture is able to handle unaligned memory access but
    other architectures are not.
    
    Fix this by doing the test the other way around -- accessing the first
    byte of a uint32_t variable though a uint8_t pointer.
