Remove pnacl_profile_observer from pnacl's use of component updater.

Remove pnacl_profile_observer from pnacl's use of component updater.

It was previously used for per-profile ChromeOS component
installation, and then changed to do cleanup from that
experiment. The files should be cleaned up by now, so remove that code.

Stop registering PNaCl for component updates on ChromeOS
also, since that was just for the cleanup.

Eventually should move to using the default component
installer w/ customization through traits, then we can
get rid of the browser_process field.
