[virt-tools-list] [virt-viewer v2 9/9] vv-file: Show 'newer-version-url' when version check fails

[Christophe Fergeau]

We currently display a generic error message when the current binary is
older than the minimum version specified in the vv file. The previous
commit added a 'newer-version-url' field to these .vv file. This commit
adds that URL to the error message if it's set.
