create-database: Skip stop-server and flush-memcached on standalone Pg.

Browse Source 
If running on a stand-alone PostgreSQL server, then supervisor does
exist -- but `stop-server` is useless, and in fact cannot run because
the Zulip directory may not be readable by the `zulip` user.

Detect if this is an application front-end server by looking for
`/home/zulip/deployments`, and use the stop-server and flush-memcached
from there if it exists.  The `create-db.sql` and
`terminate-psql-sessions` files are still read from the local
directory, but those already have precautions from being from a
non-world-readable directory, and are more obviously important to keep
in sync with the `create-database` script.
