[libcxx] Don't depend on availability markup to provide the streams in the dylib

Whether an explicit instantiation declaration should be provided is not
a matter of availability markup.

This problem is exemplified by the fact that some tests were incorrectly
marked as XFAIL when they should instead have been using the definition
of streams from the headers, and hence passing, and that, regardless of
whether visibility annotations are enabled.
