Fix the test script does not work for Docker on macOS (#297)

### Motivation

When I run `./pulsar-test-service-start.sh` on macOS m1 13.4, the
standalone failed to start due to the wrong permission of the
`test-conf` directory that is copied into the container via `docker cp`:

```
I have no name!@a00f70265760:/pulsar$ ls -l | grep test-conf
drwx------ 3  501 dialout  4096 Jun  4 13:31 test-conf
```

It seems to be a bug: docker/for-mac#1814

### Modifications

Execute `docker run` with the current username via `id -u`.
