In addition to not being an SPDX license, Unicode license also isn't
available in any of the LICENSE_PATH available in openembedded, meaning
the following warning is printed:

python3-idna: No generic license file exists for: Unicode in any provider [license-exists]

Unfortunately the license is not really explicit in the project. After
looking at the code, it seems that this license gets pulled by
idna/idnadata.py and idna/uts46data.py which are auto-generated by
tools/idna-data which downloads data from
http://www.unicode.org/Public/{version}/ucd/ and
http://www.unicode.org/Public/idna/ which are covered by
https://www.unicode.org/license.txt as mentioned in
https://www.unicode.org/copyright.html.

Comparing https://www.unicode.org/license.txt to Unicode-DFS-2016
resulted in a match so let's point to that SPDX license instead.

I looked at
https://github.com/kjd/idna/blob/master/LICENSE.md
https://pypi.org/project/idna/

and they seem to indicate that it is BSD-3-Clause so where do the
other licenses come from ?
