Official builds should be on the com.google.Chrome update product ID

Official builds should be on the com.google.Chrome update product ID, not
com.google.Chrome.framework

BUG=24836
TEST=After running Google Chrome.app, run
     ~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/MacOS/ksadmin -p.
     You should see, at the very least, tickets for com.google.Keystone and
     com.google.Chrome, and they should appear to have valid data.  You should
     not see any tickets for com.google.Chrome.framework.  If you run ksadmin
     -l, you should not get any error output.
