ceph-run: fix string comparison around --no-restart

`man test` says the stirng equality operator is `=`:

```
       STRING1 = STRING2
              the strings are equal
```

Also, we should handle the argument-less case which currently
fails:

```
$ [ $1 == "--no-restart" ]
bash: [: ==: unary operator expected
```
