Translation for alsa-utils

[GitHub issues - opened]

alsa-project/alsa-utils issue #41 was opened from Porrumentzio:

I found the [po folder](https://github.com/alsa-project/alsa-utils/tree/master/po) but seems that there are not all the translations (I know there's a Spanish localization for example). 

Is it enough to translate the po files and PR them? Or is there any other procedure?
