Magisk is adding the `SEANDROIDENFORCE` string but not including it in the AVB Footer's `original_image_size`

[TBM13]

Device: Seen after patching the Galaxy A20s' stock boot image
Android version: -
Magisk version name: v30.6
Magisk version code: 30600

After patching a Galaxy A20s boot image that contains the SEANDROIDENFORCE string, Magisk preserves it but makes the AVB Footer's original_image_size point to the start of the string, when it should actually point to the end of it.

The highlighted bytes are 11892736 in int64_t (big endian), which points to the start of the string

Magisk v29.0 does not have this issue
