7f44cebed7 Python: Add missing hidden flow 
The easiest way to implement this was to change the definition of
`module_export` to account for chains of `import *`. We reuse the
machinery from `ImportStar.qll` for this, naturally.

fd23fa94a5 Python: Remove dubious fstat* modeling 
These operate on file descriptors, and not on paths. file descriptors
doesn't fit into the rest of our modeling, so I would rather remove them
than to make it look like it's properly handled.

I also did not include any of the functions that work on file
descriptors when looking through all of `os`. So this keeps everything
consistent at least ;)

6c3aabe1df Python: Support flow through import * 
Adds result for `ModuleVariableNode::getARead` corresponding to reads
that go through (chains of) `import *`.

This required a bit of a change to _which_ module variables we define.
Previously, we only included variables that were accessed elsewhere in
the same file, but now we must ensure to also include variables that may
be accessed through `import *`.

e2652591a5 Python: Change perf fix PoorMansFunctionResolution 
Thanks @yoff, this leaves us with the following evaluation, which looks
very close to the one in the other fix (but with cleaner implementation)
-- both at 688k max tuples (although numbers are not exactly the same).
