Bug#976404: mpi4py: flaky ppc64el autopkgtest on ci.debian.net: regularly times out

[Drew Parsons]

Source: mpi4py
Followup-For: Bug #976404

mpi4py tests seem to have started passing stably on ppc64el after the
upgrade of libpmix2 from 3.2.0-1 to 3.2.1-1

(other test errors after that are other known openmpi problems,
recently fixed, not these timeout errors)

Tests are now passing reliably in both unstable and testing.

Looks like ppc64el performance has been fixed in pmix.

I think we can close this bug now.
