BUG: Capture cout and cerr from internal ctest 

When CTest detects that a test is running its own executable it
optimizes the test by using an internal instance of cmCTest instead of
creating a new process.  However, the internal instance was using cout
and cerr directly.  This redirects the output to a string stream to
avoid direct display of the internal test's output.
