Do not update SudoSu on A 7.1

[Wizzard]

I downloaded the latest version of SuperSU apk, but there is no "su" file inside. I may try to integrate the SuperSU update to system, but dont think it will work, because I tried integrating other updates to system in Link2SD, but it did not work in A7.1.

edit: I installed busybox, then I installed supersu to system and updated su binary. It have not booted then...
