x86: mask out unknown features from Xen's capabilities

If Xen doesn't know about a feature, it is unsafe for use and should be
deliberately hidden from Xen's capabilities.

This doesn't make a practical difference yet, but will make a difference
later when the guest featuresets are seeded from the host featureset.
