Fix ussuri jobs

Squashed two changes together since both are needed to fix jobs:

Resolve PEP8

No idea how this happened, but reviews started failing the
pep8 gate job. The failures are legitimate, see the commit.
I guess the pep8 tests became smarter and found these issues.

(cherry picked from commit 52ff421e3d)

Add libc6-dev to bindep

The python-builder base image was updated to no longer install
recommends. This is inline with the other Infra images and keeps
image sizes smaller. gcc recommended libc6-dev - but it turns out
we need that for limits.h for one of our depends. Add it to fix
our image builds.

(cherry picked from commit 97d027caec)
