scripts/vps-download: make it possible to set variables in vz.conf

Now one can change, say, TMPL_REPO_PREFIX from the built-in default,
by setting a new value (say your closest or local mirror) in vz.conf.

Commit ad5d1acd602b90ad73cecb99bbfc9ca54b3b86b8 was stupid,
because with it you had to set both TMPL_REPO_PREFIX and TEMPLATE_REPOS.
Now you can only set TMPL_REPO_PREFIX.
