Disable scanning the filesystem for cuttlefish-related files

This is fragile/unstable and is not yet necessary for running the device
locally. While the file list matters more for instances produced by the
fetch_cvd downloader, that already produces a file list on a separate
code path.

Test: Build and run launch_cvd
