[CI:BUILD] Packit: Disable until proved in other repos

There are concerns with Packit causing flakes and delays on Podman so
let's have Packit prove itself in other repos and only then make its way
into Podman.

See: https://github.com/containers/podman/pull/15549#issuecomment-1233230573

[NO NEW TESTS NEEDED]
