JVM: fix "module reads" check in JavaModuleGraph

There was a bug in the DFS. Whenever we encountered a "requires
transitive X" directive in some module, we recursively invoked DFS not
on X but on `dependencyName`, which is the target module that we're
trying to find the path to. And that always failed, because no module
requires itself.
