Hi,

I've recently proposed a patch to libosinfo database, and they
suggested that we add the version number to the ISO label, so the tool
can differentiate and identify the ISOs. See
https://gitlab.com/libosinfo/osinfo-db/-/merge_requests/202

The first patch adds the --label option to guix system, and it sets the
label for the boot partition.  The second patch simply uses it and adds
a --label option to the release target in the Makefile.
