rethinkdb: 2.3.6 -> 2.4.1, fix

Update patch that prevents making V8 snapshots, as those segfault.

Fix build by building only the database server. Other make targets fetch
dependencies at build time and this behaviour cannot be overriden.
Therefore, the clients and web interface are no longer built. See
rethinkdb/rethinkdb#6867.
