Allow the FUSE daemon access to Android/ on non-sdcardfs devices

Today, the FUSE daemon has access to Android/ because it has a
writable sdcardfs view.

On devices without sdcardfs, it will not have this view and will need
the two new ext_data_rw and ext_obb_rw. In future cl, we will give
these gids to access_mtp, so we optimistically add the FUSE daemon in
the condition for access to Android/
