add tool-only artifacts

Caveats:

- curl tool resides under `subdir/bin/` inside the package.
  Can be fixed locally by renaming curl to unique names, e.g.
  `curl-x64.exe` or `curl-riscv64`. Maybe even to a more globally
  unique name, such as `curl-linux-musl-amd64`.

- curl tool misses the exec permission so cannot be executed after
  unzipping. Needs `chmod +x` before doing so.
  https://github.com/actions/upload-artifact#permission-loss
  actions/upload-artifact#38

- There is no option to switch to tarball from zip.

- there is no option to skip zip and offer files as-is.
  (exec attribute would be lost in this case as well)
