4138296ec6 Python: Add test for "hidden" import * flow 
TL;DR: We were missing out on flow in the following situation:

`mod1.py`:
```python
foo = SOURCE
```

`mod2.py`:
```python
from mod1 import *
```

`test.py`:
```python
from mod2 import foo
SINK(foo)
```

This is because there's no node at which a read of `foo` takes place
within `test.py`, and so the added reads make no difference.

Unfortunately, this means the previous test was a bit too simplistic,
since it only looks for module variable reads and writes. Because of
this, we change the test to be a more traditional "all flow" style
(though restricted to `CfgNode`s).

50d3592ad3 Python: Add more complete tests of os module 
I went through https://docs.python.org/3.10/library/os.html in order,
and added all the functions that works on paths.

`lstat` and `statvfs` were already modeled, but did not have any tests.

36f14b31bc Python: Add explicit tests for kwargs 
I also renamed the arguments to match what the keyword argument is
called. It doesn't matter too much for these specific tests, but for the
tests I'm about to add, it makes things a lot easier to get an overview
of.

Oh, and a test failure :O

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 *`.

03b6ee3833 Python: Add import * test 
This test shows off a few things:

- transitive chains of `import *`
- multiple modules exporting the same name (to test for cross-talk)
