Ensure that codestyle.py always returns something on stdout to unlock m_mutex.
By returning only a "0" size on stdout, pythonstylechecking.cpp will see a "reply" and unlock the m_mutex. This avoids serious UI hangs when the stylechecker is enabled but `pycodestyle` is not installed. BUG: 392031 Differential Revision: https://phabricator.kde.org/D11474
