Incompatible with KernelSU

[patrakov]

More and more custom ROMs now integrate KernelSU as the preferred rooting method. However, Migrate does not play nice with KernelSU - it does not recognize that the device is rooted. The error is:

su: su: --: unknown option

Reproducible at least on BlissOS on x86, despite granting root to all three Migrate apps through KernelSU.

Thanks for the report. I will try to get a fix for this once root features are integrated again in v6.
