Only pin markupsafe on s390x

Commit 634bc1a pinned the markupsafe because of installations on
s390x only.  It makes sense to limit the pinning to s390x then.

That in itself would be simple enough, but, during RPM builds on
Fedora 42 (really rawhide at this time), the RPM package dependency
system provides MarkupSafe > 3.0.0 (currently 3.0.2).  So, we remove
the pinning, or else, the build would fail due to a version
requirement conflict.
