Remove shell entrypoint override from coturn - use native image entrypoint

The coturn/coturn image has its own docker-entrypoint.sh that handles
arg parsing. Overriding it with /bin/sh -c adds a failure point.
Now passing args as a clean list directly to the native entrypoint.

Also drops --external-ip for now (added back once coturn starts).
