[PATCH] ntdll/tests: Fix the XState AllFeatureSize check on old CPUs.

[Francois Gouget]

On old CPUs lacking XSAVEC, Windows 8+ does not set AllFeatureSize and
AllFeatures.

As per the comment and commit message, my understanding is that this is 
tied to the XSAVEC support in the CPU.

I removed broken() to match the xstate.AllFeatures check.
But I'm also fine with having either or both with broken(): I don't 
know what we want / can do in Wine for this.

This should fix the Windows 8.1 failures on cw-gtx560 and cw-rx460:
