Does not break at end of do while loop

The format needs to add a break before while in a 'do...while' loop.

This:

```
do {
    ...
} while (condition);
```

Should become:

```
do {
    ...
}
while (condition);
```

roslint currently complains

Someone has a fork of clang-format that claims to fix this, but I haven't investigated any further beyond encouraging them to submit it upstream:
