tests: explicitly flush output streams
Some tests fail while running with chg because they do not flush their output
streams. chgserver will make sure ui.flush is called after dispatch, but not
after {ui,repo}setup. For other non-ui streams, it should be explicitly
flushed since the request handler will use os._exit.
This patch adds explicit flushes in test-bundle2-format.t, test-extension.t
and test-obsolete.t. It will fix most test cases of them when running with chg.
