xen-cpuid does print out the list of special features, and this is helpful to
keep.
Fixes: ba6950fb070 ("x86/cpuid: Drop special_features[]")

Note - this deliberately doesn't insert ifdefary, because it is pointless. It
adds to constructing/parsing time, and nothing in Xen can gain access to this
without an explicit introduction of INIT_SPECIAL_FEATURES again, which will be
obvious during code review.
