[PATCH v2 6/7] rtemstoolkit: Fixes to the reader and writer threads for capturing

[chrisj at rtems.org]

From: Chris Johns <chrisj at rtems.org>

- Use the 'read1' file handle call to return if any data is queued
  for reading from stdout or stderr.
- Flush the stdin pipe in the writer thread.

These changes let the execute module work on Python2 and Python3.
