If Chrome is not the default browser, tell the user, unless:

- it is the first run
- the user already said not to warn him/her about it
- an info-bar is already showing.

BUG=9049
TEST=Run a new install of chrome, proceed through the first run flow, don't
     make Chrome your default browser.  No info-bar warning about Chrome not
     being the default browser should be shown.
     Restart Chrome, such an info-bar should be shown. Click the x on the
     info-bar to close it. Restart Chrome. The info-bar should be shown.
     Select "Set as default". Restart Chrome, the info-bar should not be shown.
     Start IE, make it your default browser (Tools menu, 'Internet option',
     Programs tab). Restart Chrome, it should show the default browser info-bar.
     Select "Don't ask me again". Restart Chrome, the info-bar should not be
     shown.
