docker: prefer CMD to ENTRYPOINT
Specifying watchfrr as CMD instead of ENTRYPOINT allows one to easily
override this command when starting a docker container. This allows
simple, manual testing via (e.g.) bash. With ENTRYPOINT only the
container will simply explode with an exit code if watchfrr exits.
For instance one could start a shell session in this container via:
```
docker run --name test --rm -i -t <frr-container> bash
```
The default behavior (`docker run <frr-container>` with no command
specified) is not changed.
