graph: reference/referrer node types work with graph traversal.
The graph traversal procedures in (guix graph) assume that nodes can be compared with 'eq?', which was not the case for nodes of %REFERENCE-NODE-TYPE and %REFERRER-NODE-TYPE (strings). * guix/scripts/graph.scm (intern): New procedure. (ensure-store-items, references*) (%reference-node-type, non-derivation-referrers) (%referrer-node-type): Use it on all store items. * tests/graph.scm ("node-transitive-edges, references"): New test.
