[clang] Add missing header guard in <cpuid.h>

This header has long lacked a standard multiple inclusion guard
like other headers have, for no apparent reason.  The GCC header
of the same name likewise lacks one up through release 10.1, but
trunk GCC (release 11, and perhaps future 10.x) has fixed it
(see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96238).
