Clarify EUPL SPDX expression

This isn't a license change — the code was always available under
potential future EUPL versions because of this language in the EUPL:

> Copyleft clause: If the Licensee distributes or communicates copies of the
> Original Works or Derivative Works, this Distribution or Communication will be
> done under the terms of this Licence or of a later version of this Licence
> unless the Original Work is expressly distributed only under this version of the
> Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee
> (becoming Licensor) cannot offer or impose any additional terms or conditions on
> the Work or Derivative Work that alter or restrict the terms of the Licence.

But now that reuse 1.0.0 is out, and supports SPDX '+' expressions, we
can express this more clearly in SPDX.
