Support Shizuku alongside Sui

[0xIO32]

Not a large change, but both Sui and Shizuku use the Shizuku-Api.

Currently Material Files only supports Sui.
Shizuku seems to be more maintained than sui. Shizuku supports root as well as rootless (Sui only with root).

This pr adds a small change, that allows Shizuku to be used as well.

First of all, thank you for your interest in help improving this project! However, I normally won't accept PRs for this project because I'm currently the only copyright owner for it (except for translations and maybe my company), which I think would be a nice thing to keep along. On the other hand, forcing people to give up their copyright to me is both awkward and legally-complex. So if you have any suggestions for an improvement, please feel free to comment on existing issues or open a new one!

@zhanghai If it is required for this pr to be merged, you can have the copyright.
