Python: Clean up various jump/local data flow steps
...
Removes steps from `ModuleVariableNode`s from `essaFlowStep`, and
instead puts them only in `jumpStep`. This cleans up the logic a bit.
This slightly broke the type tracker implementation (as it relied on
`essaFlowStep` being fairly liberal), so I have rewritten it to
explicitly rely on just familiar predicates for local and jump steps.
Additionally, we disallow Essa-to-Essa steps where exactly one of the
two nodes corresponds to a global variable (i.e. only local-local and
global-global steps).

I've named this `DataFlowModuleScope` since it's not really a
callable (and all of the relevant methods are empty anyway).

Some of the places where flow has disappeared look a bit suspect, so I

Most interesting to look at the custom sanitizers. Once we have use-use flow, we
should handle this case:
```
s = TAINTED_STRING
emulated_authentication_check(s)
ensure_not_tainted(s)

Python: Add example of strange DataFlow::jumpStep
...
The example code is just copied from command injection tests, that is not too
important. The important part is that `jumpStep` says there is flow from the
import of `os` to `app.route()` :O
