package/pkg-download: do not try to vendor _EXTRA_DOWNLOADS

Browse Source 
For golang- or cargo-based packages, we apply a vendoring pass after the
package's "main" download is done. Whether to vendor or not is based on
the heuristic that a specific directory exists or not; for golang
packages, we look for '/vendor', while for cargo, we look for '/VENDOR'.

This is fine for the "main" (by lack of a better term) download, but
this falls flat on its face for extra downloads. Indeed, some packages
may need to download data sets, or assets, as _EXTRA_DOWNLOADS. Those
are usually just data blobs, and are not actual golang or cargo packages;
as such they do not need to be vendored, but worse, if we try to
actually vendor them, this fails because the required files for
vendoring are missing from the archives in such data sets.

We fix that by decoupling the download for the extra download, from the
download for the main archive. We pass the post-processing option only
to the main download.

This makes the hard assumption that extra downloads will never need to
be post-processed for vendoring, of course; we hope this will always be
correct in practice. If not, we can fix it later.

[Arnout:
 - no loop needed for MAIN_DOWNLOAD, it can have only one;
 - remove superfluous backslash in the definition of MAIN_DOWNLOAD;
 - introduce _ADDITIONAL_DOWNLOADS to avoid filter-out.]
