This moves the list of removed files from .gitattributes to
tools/build-local-server-tarball because static/ and tools/ are
necessary for update-prod-static, and it seemed best to keep the
entire list in one place.

update-deployment has been replaced by upgrade-zulip for local server
instances, since it won't be running off a git repository, and
update-prod-static won't be needed since we plan on shipping minified
javascript.
When we deploy this, the deployment will fail, and then we'll need to
update the git checkout from which post-receive runs on git.zulip.net.

This has a decent amount of code copied from update-deployment, but
there's enough different that I think it's reasonable to write this
and then move some common code into the zulip_tools library.
