man page dbus example has typo

[Ian Johnson]

See http://manpages.ubuntu.com/manpages/eoan/en/man5/apparmor.d.5.html in the dbus example section for `peer=(label=unconfined)`. It has an extra closing parenthesis:

```
           # Allow receive access for all unconfined peers
           dbus receive peer=(label=unconfined)),
```

it should read:

```
           # Allow receive access for all unconfined peers
           dbus receive peer=(label=unconfined),
```
