Don't use --break-closing-brackets

I guess we didn't want this option to be enabled.

From the astyle documentation:

```
--break-closing-brackets / -y
[...]

void Foo(bool isFoo) {
    if (isFoo) {
        bar();
    } else {
        anotherBar();
    }
}

becomes (a broken 'else'):

void Foo(bool isFoo) {
    if (isFoo) {
        bar();
    }
    else {
        anotherBar();
    }
}
```
