Stop listing the app's own folders as games

We ship resources/patches.zip; .zip counts as bootable and, on an install with no
custom data root, the folder we copy assets into is also a scan root — so every
library showed a phantom game called "patches", even with an empty game folder.
Block the app-managed directories by name, as bios/covers/cache already were.
