I found the problem and a work around.

 yarnpkg why uuid
yarn why v1.22.4
[1/4] Why do we have the module "uuid"...?
[2/4] Initialising dependency graph...
[3/4] Finding dependency...

Since gitlab wants uuid 8.x, /usr/share/gitlab/node_modules has uuid 
8.1.0 and gets priority over /usr/share/nodejs/uuid

Once I force uuid 3.x for copy-webpack-plugin by

cd /usr/share/nodejs/copy-webpack-plugin/node_modules/
ln -s /usr/share/nodejs/uuid/ .

The error about uuid exports is gone. A proper fix would be to update 
node-uuid to 8.x in debian. This will need a transition and updating 
all reverse dependencies to use the new api. We can continue that 
discussion in #974587.
