Bug#909237: python-imageio: autopkgtest regression: ModuleNotFoundError: No module named 'psutil'

Version: 2.4.1-1

Dear maintainers,

With a recent upload of python-imageio the autopkgtest of python-imageio
fails in testing when that autopkgtest is run with the binary packages
of python-imageio from unstable. It passes when run with only packages
from testing. In tabular form:
                       pass            fail
python-imageio         from testing    2.4.1-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. It seems like
you forgot to add the test dependencies that you added to the build
dependencies for the same reason.

Currently this regression is contributing to the delay of the migration
to testing [1]. Can you please investigate the situation and fix it? If
needed, please change the bug's severity.
