This package was only used for the deprecated "shortid" syntax. Now that
support for this syntax was removed, we can also remove this package.
This patch deprecates and removes the package, adding temporary aliases pointing
to the new location to ease migration from docker/distribution to the new
distribution/distribution/v3. We should remove those aliases in a future update.

Go 1.16 reached end of life, so update to the current version of Go, but also
run CI on the previous version (which is still supported).
We should probably also decide wether or not we want the Dockerfiles to pin to
a specific minor version; this makes the releases more deterministic.
