fix(@nguniversal/builders): bundle critters in common engine.

critters is shipped with ES2015 this that we cannot extend it when we use the UMD because a downlevelled class cannot extend an ES2015 class as it will cause `cannot be invoked without 'new'`

With this change, critters will be included in the UMD bundle and downelevelled which would result in us being able to extend it.

Closes angular#1970
