Pixel Props: post #870 — TG.ME

- No longer wipes
packages-warnings.xml (that was only causing repeated warning dialogs and has nothing to do with DroidGuard/Play Integrity)
- System packages (system="true") are now properly skipped instead of being marked as Play Store installs
- packageSource="2" is now added when missing (not just replaced)
- Also handles isOrphaned="1" and installInitiatorUninstalled="1" in addition to "true"

Under the hood: safer line-by-line processing (slower) + updated abx2xml/xml2abx binaries (now with riscv64 support).
