Before this patch, calling `image.Children` on an image built with
BuildKit would produce unnecessary `encountered unknown type
application/vnd.in-toto+json; children may not be fetched` debug logs,
because the media type is neither a known layer or config type.
Make the `image.Children` aware of the attestation layers and don't
attempt to traverse them.

There's a couple spots where we know exactly how large
the destination buffer should be, so pre-size these to
avoid any reallocs to a higher capacity.

This TODO was added in 9e6db71954, at which time
the reference package was part of the docker/distribution (registry) repository.
The reference package has moved to a standalone module, which has been in use
since 4923470902, so this should no longer be a
concern.
