add: override for bower-angular-cookies 1.3.0-rc.1

not exactly sure, if i should have included `angular` as a dependency .. like e.g. the `angular-mocks` override does, which would then look like:

```
{
  "main": "angular-cookies",
  "shim": {
    "angular-cookies": {
      "deps": ["angular"]
    }
  },
  "dependencies": {
    "angular": "1.3.0-rc.1"
  }
}
```

my local test with `jspm install github:angular/bower-angular-cookies -o "{ main: 'angular-cookies' }"` worked though.
