require golang-any to be 1.16 or later in debian/control

This package requires at least golang 1.16 to build.

In buster and bullseye there is only 1.15 and with that version builds fail with "package io/fs is not in GOROOT".

With 1.16 this issue is gone.

The package could be built with DIST=bullseye-backports which pulled in 1.17.

This is to prevent this issue the next time we build.
