Put .hmac files into a separate directory
    
    Putting the .hmac files into the same directory as the checked binary
    causes rpmlint errors and is generaly not a good idea (there could be a
    multilib conflict).
    
    Since dracut is already hard-coded to search for them in
    /lib(64)?/fipscheck and /lib(64)?/hmaccalc, let's just drop them there.
