Do not report data races between symbols defined in class and its selftype

Analogous to the previous situation where we do not report a data race
if the previous symbol comes from a superclass, we now do the same if
the previous symbol comes from a given self type. Makes overrideDataRace.scala pass,
and finally enables stdlib test with TraverableViewLike.scala added.
