In the current API, we have some set operations: join, intersect and
subtract. Both join and subtract receives two DRM format arrays and save
the result in the first one.
For the intersection we have a slightly different approach, what makes
the API weird. We don't save the result in the arguments, instead we
return a new array with the result.
Modify weston_drm_format_array_intersect() in order to make it similar
to the other two set operations.

In commit "libweston: add struct weston_drm_format" we've added an API
to store and manage DRM formats and modifiers. As it has a couple of set
operations that are not so obvious, this adds unit tests to ensure
correctness. In the future we may expand this API and also improve
performance, so it is important to have this.
