Add a function to provide the list of third-party directories which are incompatible with Android.

For most directories, we use a regex of whitelisted licenses to parse the 'License' field from the metadata. In some case, for example, where a custom license is used, we rely on a new 'Android Compatibility' field.

This functionality will be used by the snapshot tool, which will exclude these incompatible directories from the snapshot in the Android tree.
