Title: support get_package_version for smartos

Hi,

I write `#get_package_version` for joyent smartos.

## Case success

```
> backend.check_os
=> {:family=>"SmartOS", :release=>nil}

> backend.get_package_version('openssl')
=> #
```

## Case fail

```
> backend.get_package_version('openss')
=> #
```
