[res] Remove global overlays from registered lib paths

When calling Resources.registerResourcePaths(), the passed
application info object contains all asset paths for the lib,
including global system overlays, theming FRROs and so on.

This change filters out those that are common with the current
app's assets - they are already a part of all resource objects
and don't need to be registered and added separately.

This fixes an issue of retaining global overlay paths that got
updated after the register...() function call
