selinux shim does not seem to work with Fedora 29

[tyll]

These commands work outside a virtualenv (created with tox)

python3 -c "import selinux; print(selinux.is_selinux_enabled())"
python -c "import selinux; print(selinux.is_selinux_enabled())"

but they do not work inside with the selinux shim installed.

python -c "import selinux; print(selinux.is_selinux_enabled())"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: module 'selinux' has no attribute 'is_selinux_enabled'

Is there something special that needs to be done to get this working? I would like to run molecule inside a tox virtualenv but am hitting ansible/molecule#1724

#3 makes the module return a proper error in this situation.
