Um, Citation needed?

I don't see any evidence for this in the kselftest documentation, nor
do I see any evidence of this in the kselftest Makefiles.

There exists test modules in the kernel that run before the init
scripts run --- but that's not strictly speaking part of kselftests,
and do not have any kind of infrastructure.  As noted, the
kselftests_harness header file fundamentally assumes that you are
running test code in userspace.
