py3: flush stdout

This avoids buffering due to mixed print() and sys.stdout.write() by
profiling code.

And with this, test-profile.t passes on Python 3 \o/.

Honestly, I'd be shocked if there weren't more Python 3 encoding issues lingering
in the profiling code. That code isn't super high quality and doesn't seem to have
thorough test coverage.
