Revert revert of 146149 - Don't pass the connector check policy flag along.

Revert revert of  146149 - Don't pass the connector check policy flag along.

If a browser is running, and the service process is running the connector, the
connector will occasionally start up a chromium process to check the connector
enablement policy. The flag to do so would get passed to a running browser, if
present, and there is a path through the policy check code that could cause the
browser to quit.

This patch prevents the policy check flag from being passed on; the started
process will be very short lived and does a silent launch.

This is a slight tweak of https://chromiumcodereview.appspot.com/10666010, which
had to be reverted. The new test should not be run on CrOS, and switched to
properly use content::WindowedNotificationObserver (where it was moved to).
