ROADMAP: Remove printable/compiled-spec target

The bulk of this was addressed by 4ee036f (*: printable documents,
2015-12-09, opencontainers#263).  Any remaining polishing of that workflow seems
like a GitHub-issue thing and not a ROADMAP thing.  And publishing
these to opencontainers.org certainly seems like it's outside the
scope of this repository (although I think that such publishing is a
good idea).
