Bug#1112181: openmpi-bin: pmix doc warnings in stderr cause test failure

[Drew Parsons]

Package: openmpi-bin
Version: 5.0.8-3
Severity: serious
Justification: debci

openmpi 5.0.8-3 readjusted the pmix configuration to allow openmpi to run
without the external pmix 6 library.

It looks like some small pmix detail got missed. Running mpiexec gets a
warning about missing pmix (and prte) help files

$ mpiexec -n 1 date
--------------------------------------------------------------------------
Sorry!  You were supposed to get help about:
    unavailable
But I couldn't open the help file:
    /usr/share/pmix/help-pcompress.txt: No such file or directory
    /usr/share/prte/help-pcompress.txt: No such file or directory.
Sorry!

It's only a warning, but the problem is that it's sent to stderr.
This means that debci (autopkgtest) tests fail if they're not
configuring to ignore stderr.

This includes openmpi's own debci tests, which are now failing with 5.0.8-3
