`test_dtrace` fails on s390x Fedora buildbots

[ZeroIntensity]

Bug report

Bug description:

Saw in #157045 (specifically 5693c85). Failing builds seem to be only on Fedora s390x. For example:

• https://buildbot.python.org/#/builders/1634/builds/579
• https://buildbot.python.org/#/builders/1666/builds/579
• https://buildbot.python.org/#/builders/1643/builds/580
• https://buildbot.python.org/#/builders/1640/builds/582
• https://buildbot.python.org/#/builders/1652/builds/583
• https://buildbot.python.org/#/builders/1630/builds/674

Here's the traceback:

I'm unsure whether this is a known issue already, but I couldn't find any existing reports.
