backslashxx d702e746e3 kernel: throne_tracker: avoid cross-fs traversal using s_magic check (#2633) ...

Skip directories that does NOT have the same magic as /data/app.
This is to avoid scanning incfs and any other stacked filesystems.

While this is way dumber, it's way cheaper.
no kern_path(), no missable path_put(), no ref handling.

This supercedes
