On Fedora-derived systems (and possibly others), selinux can prevent podman from running the way we need it to for our tests to work.
Loading this module (hopefully) allows you to keep selinux enabled and still be able to run our tests.
To use it, just run:
./build.sh
...which will build the module. Then run:
sudo semodule -i ansible-podman.pp
to insert and enable the module.
