Bug#877726: test_progress regression with WoLpH/python-progressbar 3.34.3

[Levente Polyak]

Package: diffoscope

There is a test failure when using python-progressbar 3.34.3.
It expects 'ETA' to be in the output, however the err seems to be empty
and the stdout is atteched (does not contain ETA, maybe because its
already at 100%).
