[Fedora-spins] Adding SELinux permissive to the AOS spin

The board would like to see SELinux enabled on the spins. Although it does not appear to be a formal requirement, I woule like to add it to ensure that the spin gets approval. This patch will make enable it permissive. I have tested this withe appliance tooling and it causes no issues. Can you all please approve this, push it to the repo, and I will re-apply to the board? Thanks! -- bk
