Bruno Pinto f57ef1b4b5 Suppress basename usage output
When using basename without any arguments, a usage helper as following
is displayed:

```
usage: basename string [suffix]
       basename [-a] [-s suffix] string [...]
```

When listing the installed packages, if no theme was installed (e.g.
first installation), the `themes/` folder are empty and the usage helper
is displayed. This change addresses it by suppressing the message.
