Disable listener hot reload updates on standalone macOS

*Description*:

On macOS, the OS cannot reuse the port hence the following error keeps appearing as error message. IMO, EG can simply stop listener updates on macOS.

The limitation is documented on `enable_reuse_port` field on the official doc: https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/listener/v3/listener.proto
