Make the nautilus extension conditional

... and disable it from being built, as suggested by rishi.

The nautilus extension provides tagging functionality and is not related
to search at all -- and none of the core apps use tagging at the moment.
Since we don't need it, disable the package to make tracker package
easier to bootstrap (circular tracker-nautilus-tracker dep).
