[PULL 13/17] tests/functional: drop datadrainer class in reverse debugging

["Alex Bennée" <alex.bennee@linaro.org>]

From: Daniel P. Berrangé <berrange@redhat.com>

The reverse debugging test uses the avocado datadrainer class to
create a background thread that reads from the console socket and
dumps it via python logger.

Most tests log console output as a side effect of doing calls
to match strings, but this test never tries to match anything.

This isn't critical, so just drop the functionality.
