graph-depends: remove support for "unknown" packages

The "unknown" packages mechanism was used to render packages that did
not implement the make <pkg>-show-depends target, i.e the packages
that were not yet converted to one of the package infrastructures.

Since now all packages have been converted, we can remove this
"unknown" packages feature.
