GNU identifiers like 'GPL-N+'.  This commit adds support
for other uses of '+', such as 'AFL-2.0+' and 'LPPL-1.0+'.

Strictly speaking, '+' is an operator, not part of the SPDX license
identifier, but it is useful to handle it here.

* guix/import/utils.scm (spdx-string-&gt;license): Support '+' operator.
* tests/import-utils.scm ("spdx-string-&gt;license"): Test it.
