Set execute permissions for startup scripts

[woodpekr]

Add execute permissions to start_vernemq and join_cluster scripts

Otherwise, the following error will be reported at startup

docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: exec: "start_vernemq": executable file not found in $PATH

@zhuomuniao1986 Thanks, it seems this was never necessary before, though. Anything special in your environment?

There are no special.

I tested it again, and the issue can be reproduced. The image can be created successfully, but an error occurs when starting the container.
