Bug#1006790: python-unicodedata2: FTBFS without network access

[Daniel Schepler <dschepler@gmail.com>]

Source: python-unicodedata2
Version: 14.0.0+ds-7
Severity: serious

See https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/python-unicodedata2.html
:  (I also see the same error in my custom build environment based on
sbuild, but using a systemd-nspawn container with network access
disabled.)
