Don't show Zulip.com terms on other sites

While we already don't link to /terms anywhere on the site, they can still be
accessed if you navigate to /terms directly. Now, those routes will only be
exported on the Zulip.com service.

We should ideally provide a mechanism for deployments to specify their own
terms without modifying source code; in the interim, sites that have already
customised the provided Zulip.com terms can simply carry a patch reverting this
commit.
