[pkg-go] Bug#871566: swarmkit FTBFS: cannot find package "github.com/docker/docker/api/types"

[Edmund Grimley Evans]

The build failure quoted above is not reproducible with the current
state of sid, I think. However, it is still not possible to build
swarmkit for a different reason: an indirect dependency on
golang-github-juju-ansiterm. See #886613 and the "Dependency
installability problem for swarmkit" on arm64 and other architectures:
