Disable fs:largeFiles checks until the images are updated with findutils

[tobybellwood]

The fs:largeFiles check (https://drutiny.github.io/2.3.x/audits/DrutinyAuditFilesystem/#largefiles)
uses a variant of the find command that is not natively supported on busybox (it requires https://pkgs.alpinelinux.org/package/v3.9/main/x86/findutils to provide the -M size option and the printf command)

As such, it should be disabled in the checks until the apk has been added to the images.

In the meantime, the Drupal:largeFiles check provides file sizes via the database.

Likewise fs:SensitivePublicFiles checks also rely on findutils
