CMUpdater: collapse statusbar when upgrading from notification

When clicking "Upgrade" from the notification action after
the updater successfully completes a download, the reboot
dialog would pop up underneat the statusbar, but it would
never be collapsed to let the user know.

This patch collapses the statusbar after the reboot
process begins.

CMUpdater: use different notification icon when download fails

Use case:
1. User starts downloading update and puts phone away
2. After some time, user looks at the phone and sees CMUpdater icon.
3. User pulls the notification shade expecting the update ready to be installed.
4. CRAP, IT FAILED!

This patch changes "failed" notification icon to a default warning icon, so user
will know that something went wrong. Prevents frustration from incomplete updates.
