[PATCH 02/17] CLI/git: drop support for python < 3.2

[David Bremner <david@tethera.net>]

Debian stable had python 3.4.2 3 releases ago (approximately 6 years
ago), so attempting to keep track of the changes in python is probably
no longer worthwhile. We already require python 3.5 for the
python-cffi bindings (although those are not yet used in notmuch-git).
