bash-completion: add remote completion for --ostemplate

Since now vzctl have a feature to download an OS template
right during vzctl create, it makes sense to complete --ostemplate
argument by not only templates in /vz/template/cache, but also by
those available for download.

Use just-added vps-download --list functionality for that.
