ImportError: cannot import name '_selinux' from 'selinux' with swig-4.0.0

[Petr Lautrbach]

Hello all,

selinux python module can't be imported when it's built using
swig-4.0.0:

>>> import selinux
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.7/site-packages/selinux/__init__.py", 
  line 13, in <module>
    from . import _selinux
ImportError: cannot import name '_selinux' from 'selinux' 
(/usr/lib64/python3.7/site-packages/selinux/__init__.py)
>>>

You can see it at [1]

The reason is that swig changed the way how it generates 
__init__.py.
Now it uses:
from . import _selinux

I've started to rewrite libselinux in order not to build and 
install
python bindings manually, but to use python distutils [2]. It 
still fails
on travis but I was able to built it and use it on my local 
rawhide machine.
