Magisk Canary v21408

Changelog:
- [MagiskBoot] Fix bug when unpacking lz4_lg compressed boot images
- [App] Fix boot image/tar file patching on some configurations

How to Use the APK for Recoveries:
- In general, it is recommended to install and uninstall Magisk through the Magisk app.
- However, if you insist to use custom recoveries, rename the Magisk APK's .apk file extension to .zip. TWRP should then be able to directly flash the zip file.
- If you have trouble renaming the file extension on PC, rename the file with TWRP's built-in file manager.
- To uninstall in recovery, rename the zip file to uninstall.zip before flashing it.
