`ActiveSupport::Concern` uses an unusual way to chain class methods,
which does not exactly follow how Ruby chains the classes.

In particular, it's like Concern reinvents the object model and
builds the ancestors chain in runtime, rather than at the compile time.
This for sure introduced a lot of culprits.

This fix is aiming for restoring the class methods for the module
which is defining the class methods. To be specific, consider this case:

``` ruby
module Base
  extend ActiveSupport::Concern

  class_methods do
    def f
    end
  end
end

module Derived
  include Base
end
```

What would you expect for this?

``` ruby
Base.f    # => NoMethodError
Derived.f # => nil
```

With this hack, it'll allow `Base.f` to work, which can make `override`
check for class methods. Before this hack it'll not work due to this
disparity.

Since so far the only place we really need this is when we're checking
`override` with those class methods, we don't have to take the risk to
change how it works in production, but just how we check `override`.

This hack is needed for `override` because we're checking `prepend` at
where it's defined, not at where it's eventually included into a class,
and that's where Concern does the magic.

If one day we can stop using `ActiveSupport::Concern`, and just do
plain old good Ruby, we'll be free from all those wild hacks.
