vztmpl-dl: add --list-remote, --list-local

Previously, we only had --list argument, to list templates
available for download. It makes sense to also add an ability
to list local templates (--list-local) and all templates (both
local and available for download) (--list-all).

While we're at it,
* rename --list to --list-remote;
* modify usage and man page accordingly;
* fix bash_completion for vzctl accordingly.
