An sqv backend is now available in apt-team/apt!409 and in
experimental in apt 2.9.17+exp1.

Note that the experimental upload only supports architectures
with sqv available. There is no fallback yet.

The plan is to detect if sqv is available at build time, by
build-depending on sqv for the correct set of architectures,
and then generate a `Depends: sqv` for those architectures,
and `Depends: gpgv` for other (ports) architectures.

The sqv binary is about 2MB large when optimized for size,
and provides good feedback when a key cannot be verified.
