Fix UWSGI logging to stderr

All of uwsgi's logs were going to stderr, while the python logs
were going to stdout. This caused redirection to be unintuitive
by only redirecting the python logs. This change makes all output
stdout instead of it being split half and half with stderr even
though there were no errors.
