I guess you could do that in the spec file of the package that owns this file,
e.g. gdm, based on an arch-specific branch. Or require an additional
fix-package which does this change? Have you checked for any upstream bugs
describing this problem?

Regarding the openQA test, as we have support for logging in users, e.g. see
the use of the variable NOAUTOLOGIN, you might be able to detect the problem
and workaround it in first_boot (or the helper function wait_boot)
