Launch Google Update on uninstall.

So it can self-destruct if Chrome (or Chrome Frame) was the last Omaha-managed product on the system.

BUG=114786
TEST=Install Google Update 1.3.21.105 or later and Chrome w/ --verbose-logging.  Uninstall Chrome and see that Google Update vanishes immediately.  Take a look at chrome_installer.log and look for messages related to Launching Google Update's uninstaller.
