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 is a workaround for Ultra-Legacy kernels where upstream's
method fails.
Seems doing 50+ kern_path() calls is a bad meme.
This supercedes `throne_tracker: avoid cross fs access (tiann#2626)`
