*: Allow specifying extra URLs for torcx packages

Torcx manifest may contain paths and URLs as locations of
packages. There are two kinds of packages - vendored and
extra. Vendored packages normally have two locations - path to the
directory inside the image where the package is (which is why it's
called vendored), and a URL to the package on some remote
server. Extra packages only have a URL. But the URLs are added only
when we tell the build_torcx_store script to upload the packages at
the same time, which is what the old build pipeline was doing. With
the new pipeline, the upload happens as a separate step, thus the
upload is disabled when invoking build_torcx_store, and so the
packages are not getting URLs set. This change went unnoticed, because
a kola test checking the generated torcx manifest was only checking if
there is at least one location, either path or URL, and all the new
releases have no extra packages, only vendored ones.

When backporting the new pipeline to old LTS, the kola tests started
to fail, because old LTS had one extra package, and this is how I
noticed the problem.
