Remove all modularity support

[cgwalters]

Derived from #4937

Part of https://fedoraproject.org/wiki/Changes/RetireModularity

It's dead, so let's remove all the code. I think this may
cause things to silently do nothing if folks have modules
layered, but at least server side builds will just stop working.

[jmarrero]

We are testing for the version ID, so either we change that or we use a package from the same version(f40)

[jmarrero]

looks we need to remove:

        let modules = extensions.modules.unwrap();
        assert!(modules.enable.unwrap().contains("virt:av"));
        assert!(modules.install.is_none());

and

        let modules = extensions.modules.unwrap();
        assert!(modules.enable.as_ref().unwrap().contains("foo:stable"));
        assert!(modules.enable.as_ref().unwrap().contains("virt:av"));
        assert!(modules.install.is_none())

Yup, happy to see it go. On the origin side, possibly we need code to actually drop the dead keys so they don't just hang around (I mean, it's harmless but it's also misleading).

[jlebon]

This is continued in #4937 again.

[cgwalters]

They're different, the change in 1ba3a7b just deletes the entrypoints to minimize code churn. This PR deletes it all.

From failed logs, might need to remove related in src/libpriv/rpmostree-util.cxx

[cgwalters]

OK, if CI passes on this one I think we can call it good to go.
