contrib/spec/podman.spec.in: Drop README-hooks

I'd tried to drop it here with ea41561 (hooks/docs: Add oci-hooks.5
and per-package man page building, 2018-05-15, #772), but had missed
the reference added in 796d6c8 (Add python3 package to podman,
2018-05-17, #791) when rebasing around that package.  With this
commit, I'm killing it again ;).
