[Reproducible-builds] Bug#797855: spice-gtk:spice-common/common/generated_* not reliably generated from source

[Chris Lamb]

Source: spice-gtk
Version: 0.29-1
Severity: serious
Justification: fails to build from source

Hi,

The spice-common/common/generated_* files are not reliably regenerated
from source.

Depending on the timezone of the build system, the package may FTBFS as
the `spice-common/python_modules/codegen.py` tool used to regenerate
these files requires python-six which is not included in the
Build-Depends.

(ie. I don't believe simply including python-six as a build-dependency
entirely resolves the issue)

Here's the build running in, for example,
TZ=/usr/share/zoneinfo/Etc/GMT-14
