[PATCH 1/3] rteval: cyclictest.py Enable logging cyclictest output

[Punit Agrawal <punitagrawal@gmail.com>]

From: Punit Agrawal <punit1.agrawal@toshiba.co.jp>

The cyclictest.py module uses a temporary file to store the output
from "cyclictest" which is deleted at the end of the run. As the
collected log contains more information than what is being reported by
rteval it would make sense to persist the logs. It can also be useful
to sanity check the results reported by rteval.

With this goal, create a persistent file named
"cyclictest.stdout" (instead of a tempfile) to capture the cyclictest
logs. The file is stored in the same location as the logs from the
other modules.
